This book was released on 2021 with total page 879 pages. Available in PDF, EPUB and Kindle. Book excerpt: Direct functionalization of C0́2H bonds reduces the number of synthetic steps for a target molecule enhancing efficiency and avoiding undesired waste material. Iridium catalyzed C-H activation-borylation (CHB) is an established method to access aryl boronic esters. Regioselectivity challenges can arise when multiple hydrogens are present in the molecule. This thesis describes the design of novel strategies to selective direct the CHB to one specific position.Ortho selective CHB has the challenge to go against the traditional CHB selectivity dictated by steric effects. Previously, our group reported a strategy for highly ortho-selective CHB of anilines by using a small B2eg2 (eg = ethanediol) as the borylating reagent. However, the products were unstable and transesterification with pinacol was needed. Chapter 2 builds upon this issue and presents a solution based on the modulation of the size of the boron partner. Small diboron partners retain the high ortho regioselectivity for CHB of aniline but larger borylating reagents generate more stable products. In our estimation, B2bg2 (bg = 1,2-butanediol) represents the best balance of reactivity, regioselectivity and stability.Remote functionalization including para selective reactions are difficult because a potential directing group would be far from the desired reactive site. Chapter 3 details how para CHB of tetraalkylammonium sulfates and sulfamates have been achieved using bipyridine-ligated Ir boryl catalysts. Selectivities can be modulated by both the length of the alkyl groups in the tetraalkylammonium cations and the substituents on the bipyridine ligands. Ion pairing, where the alkyl groups of the cation shield the meta C8́2H bonds in the counteranions, is proposed to account for para selectivity. The 4,4'-dimethoxy-2,2'-bipyridine ligand gave superior selectivities.The next chapter describes how intramolecular hydrogen bonding (IMHB) can lead to steric shielding effects that can direct CHB regiochemistry. Bpin/arene IMHB can promote remote borylations of N-borylated anilines, 2-amino-N-alkylpyridine, tetrahydroquinolines, indoles and 1-borylated naphthalenes. Our studies support molecular geometries with the Bpin orientation controlled by a C-H0́Ø0́Ø0́ØO IMHB. Calculated rotation barriers to displace the Bpin group are above 4 kcal/mol, suggesting that the planar ground conformation of the borylated arenes is retained during CHB. This study informs researchers to evaluate not only inter- but also intramolecular noncovalent interactions as potential drivers of remote CHB regioselectivity.The borylated products from CHB can be further manipulated in Suzuki-Miyaura cross-coupling (SMC) with aryl halides as the typical electrophilic partner. Aryl imidazolylsulfonates are nongenotoxic electrophiles that can be used in palladium catalyzed SMC to avoid halogenated materials. Chapter 5 shows the efforts towards a nickel-catalyzed SMC of aryl imidazolyl-sulfonates. Results show considerable amounts of the corresponding diarylsulfate formed during the reaction. Interestingly, the diaryl sulfa byproducts were found to be competent electrophilic partners for both palladium and nickel-catalyzed SMC.In summary, this thesis presents novel methodologies to access challenging transformations as the para borylations of phenols, anilines and benzyl alcohols. This was possible by the analysis of the different components of the catalytic system: design of ligands, diboron partners and substrate directing groups and how they interact during the reaction. Finally, the potential of aryl imidazolylsulfonates as nongenotoxic pseudohalides in nickel-catalyzed SMC was evaluated.

Available in PDF, EPUB and Kindle. Book excerpt: The following dissertation discusses the development of novel methodology for the catalytic borylation of C-H bonds and includes in-depth studies on the mechanism and selectivity of these synthetic transformations. These methods include the borylation of heteroaryl C-H bonds, the selective borylation of benzylic C-H bonds, and the directed and undirected borylation of unactivated alkyl C-H bonds. Chapter 1 contains a comprehensive review of C-H borylation methodology. This review focuses on the initial development of catalytic C-H borylation and on the state-of- the-art of methodology for the undirected and directed borylation of aryl, benzylic, and alkyl C-H bonds. Additionally, this review highlights knowledge gaps and unsolved challenges. Furthermore, this review provides the author's opinion on future directions for research on the borylation of C-H bonds. Chapter 2 describes the study of the iridium-catalyzed borylation of heteroaryl C- H bonds. Contained is an examination of the scope of the borylation of heterocycles containing more than one heteroatom and rules for predicting the site-selectivity of this reaction. Also included are experimental and computational studies that reveal the mechanism of this reaction and the origins of the observed regioselectivity. Chapter 3 discusses the development of the selective borylation of the primary benzylic C-H bonds of methylarenes. Key to this development was the discovery that the combination of a novel iridium catalyst and a silylborane allows for the selective borylation of benzylic C-H bonds over aryl C-H bonds. Experimental and computational studies that investigate the origins of this selectivity are also discussed. Chapter 4 discusses the development of the iridium-catalyzed, hydrosilyl-directed borylation of alkyl C-H bonds. This methodology allows for the diastereoselective borylation of secondary alkyl C-H bonds under relatively mild conditions. Chapter 5 explores the effect of ligand structure on the rates of alkyl C-H borylation catalyzed by Ir-phenanthroline complexes. Experimental and computational studies reveal that in addition to the relative electron-donating ability of phenanthrolines, weak interactions involving the phenanthroline in the transition state of the turnover- limiting step for the borylation of alkyl C-H bonds can have a large impact on the relative rates of alkyl C-H borylation catalyzed by various Ir-phenanthroline complexes.

This book was released on 2013 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: The studies reported in this dissertation illustrate a few selected examples of using density functional theory (DFT) calculations to investigate various aspects of iridium-catalyzed reactions and ring-opening of bicyclic cyclobutene rings. These computational predictions not only reproduce and explain experimental results and offer insights to reaction mechanisms, but also provide theoretical models to predict reactivity, regio- and stereoselectivities. Chapter 1 is a review surveying the literature of iridium-catalyzed borylation reactions. Emphasis is placed on iridium-catalyzed borylation of alkenes and arenes. In particular, I discuss the history leading up to the current catalyst systems for iridium-catalyzed borylation reactions, and regioselectivity of borylation for a number of different substrates. Despite the large amount of work on iridium-catalyzed borylation reactions, this review shows that there is still much to be understood regarding the origins of observed regioselectivities. Chapters 2 and 3 describe theoretical investigations of Ir(III)-catalyzed borylation reactions. The origins of regioselectivities observed in the borylation of pyridine are discussed in Chapter 2. The high selectivity for borylation at the 3- and 4- position of pyridine is attributed to the formation of a Lewis acid-base complex between pyridine and either boron species or iridium species in solution. The origins of regioselectivities for the iridium-catalyzed borylation of substituted arenes and 5-membered heterocycles are discussed in Chapter 3. The distortion/interaction model was employed to understand the origins of the selectivities in these reactions. Computations revealed that regioselectivity is mainly controlled by differences in the interaction energies between the iridium catalyst and arene carbon. Chapter 4 illustrates a theoretical study of ring-opening in strained, trans-substituted cyclobutenes. The torquoselectively preferred outward ring-opening products are unable to form due to ring strain inherent in 9- and 10-membered macrocyclic (E, E)-1,3-dienes. As a result of this study, I propose a general methodology for stereoselective synthesis of macrocyclic (Z, Z)-1,3-dienes termed strain-induced thermal selectivity (SITS).

This book was released on 2019 with total page 521 pages. Available in PDF, EPUB and Kindle. Book excerpt: The studies in this dissertation are aimed at uncovering reactive and selective Ir-catalyzed C-H borylation (CHB) catalysts. Due to the high versatility of organoboron species, green methodology to produce the C-B bond is poised to support a myriad of subsequent transformations. These transformations include Suzuki couplings, aminations, oxidations, halogenations, cyanations, and trifluoromethylations.Typical iridium catalyzed CHBs proceed through an iridium trisboryl with a bidentate ligand such as bipyridine or 1,10-phenanthroline. The selectivity of these standard catalysts is generally driven by sterics; however, many methods of overcoming the steric bias have been developed in the two decades since the first thermal catalytic C-H activation borylation. These methods include both inner- and outer-sphere directed mechanisms. Outer-sphere directed borylations have been accomplished by leveraging hydrogen bonding, Lewis acid-base, and ion-pairing as directing elements. In general this reactivity is activated by precise design of the bidentate ligand framework.Herein is reported a subtle electrostatic interaction to direct ortho-borylation of phenols by simply switching boron source from the common B2pin2 (pin = pinacolate) to B2eg2 (eg = ethyleneglycolate). This electrostatic interaction was revealed by a careful computational analysis of key C-H activation transition states. Understanding gained by the computational studies led to the redesign of the boron source which enabled by selectivities of > 99% ortho borylation. This methodology was extended to the highly selective ortho-borylation of anilines, and the underlying mechanism has been interrogated.Currently, iridium based catalysts have been generated to borylate ortho, meta, and even para to a variety of classes of substrates; however, control of selectivity can breakdown in many fluorinated arenes without a directing group. These substrates are challenging because the fluoro moiety being similar in size to a hydrogen offers little in the way of steric bias. While working to overcome these challenges, a serendipitously discovered hydrazone based ligand was discovered. Exploration of the catalysts generated by this ligand revealed not only impressive activity rivaling dtbpy but also incredible selectivity for meta to a fluoro group.In general iridium CHB catalysts selectively activate sp2 C-H bonds leaving all sp3 C-H bonds intact; however, a method to turn on sp3 C-H activation would be desirable. It was reasoned that a directing group able to increase the effective concentration of the iridium catalyst near a C(sp3)-H bond may enable this transformation. Indeed, it was discovered that catalysts able to accept amide directing groups were able to selectively borylate compounds with amide N-methyl substituents.

Book excerpt: 'Overall, this collection of case studies provides an outstanding starting point for understanding the ethics of chemistry. It is an extremely important contribution to the study of chemical ethics … Ethics of Chemistry is a key resource for educators interested in integrating ethics instruction into their chemistry curricula … an important foundation for equipping students with the moral judgement and analytical skills necessary to contend with the ethical issues they are likely to face in their professional lives.'Nature Chemistry'… the book offers a general introduction to many relevant topics concerning the values, responsibilities, and judgements in (and of) chemistry. The volume could be helpful for university students and teachers or even general readers interested in the ethics of chemistry.' [Read Full Review]José Ramón Bertomeu-SánchezAmbixAlthough chemistry has been the target of numerous public moral debates for over a century, there is still no academic field of ethics of chemistry to develop an ethically balanced view of the discipline. And while ethics courses are increasingly demanded for science and engineering students in many countries, chemistry is still lagging behind because of a lack of appropriate teaching material. This volume fills both gaps by establishing the scope of ethics of chemistry and providing a cased-based approach to teaching, thereby also narrating a cultural history of chemistry.From poison gas in WWI to climate engineering of the future, this volume covers the most important historical cases of chemistry. It draws lesson from major disasters of the past, such as in Bhopal and Love Canal, or from thalidomide, Agent Orange, and DDT. It further introduces to ethical arguments pro and con by discussing issues about bisphenol-A, polyvinyl chloride, and rare earth elements; as well as of contested chemical projects such as human enhancement, the creation of artificial life, and patents on human DNA. Moreover, it illustrates chemical engagements in preventing hazards, from the prediction of ozone depletion, to Green Chemistry, and research in recycling, industrial substance substitution, and clean-up. Students also learn about codes of conduct and chemical regulations.An international team of experts narrate the historical cases and analyse their ethical dimensions. All cases are suitable for undergraduate teaching, either in classes of ethics, history of chemistry, or in chemistry classes proper.
