Available in PDF, EPUB and Kindle. Book excerpt: The series Topics in Current Chemistry Collections presents critical reviews from the journal Topics in Current Chemistry organized in topical volumes. The scope of coverage is all areas of chemical science including the interfaces with related disciplines such as biology, medicine and materials science. The goal of each thematic volume is to give the non-specialist reader, whether in academia or industry, a comprehensive insight into an area where new research is emerging which is of interest to a larger scientific audience. Each review within the volume critically surveys one aspect of that topic and places it within the context of the volume as a whole. The most significant developments of the last 5 to 10 years are presented using selected examples to illustrate the principles discussed. The coverage is not intended to be an exhaustive summary of the field or include large quantities of data, but should rather be conceptual, concentrating on the methodological thinking that will allow the non-specialist reader to understand the information presented. Contributions also offer an outlook on potential future developments in the field.

This book was released on 2017 with total page 241 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Iron catalyzed C-C cross coupling reactions have drawn significant interest as more versatile and cost effective alternatives to traditional precious metal catalysts, however limited mechanistic understanding of these reactions has been reported hindering rational optimization of these systems. The use of electron paramagnetic resonance, magnetic circular dichroism, Ms̲sbauer spectroscopy, and density functional theory, in addition to GC, NMR, and X-ray crystallography, are applied in the examination of structural and mechanistic aspects of in situ iron cross-coupling chemistry with a focus on elucidating how different nucleophiles, reaction additives and protocols affect reactivity. In Chapter 2 and 3, initial studies presented investigate iron-bisphosphine catalyzed cross-coupling of aryl nucleophiles with alkyl halides. These studies describe the iron species formed in situ and provide insight into the active species of catalysis as a function of nucleophile in both Kumada and Suzuki-Miyaura cross-coupling reactions. In Chapter 4, further studies investigate simple iron salt catalysts with methyl and ethyl Grignards for direct determination of iron species present in solution and their reactivity with electrophile. Additional studies further probe the effect of N-methylpyrrolidone as a co-solvent. In conclusion, it is shown in these studies the novel utility of these direct spectroscopic probes in monitoring in situ iron speciation and reactivity with electrophile. Furthermore, through monitoring of reactions we can also define why key aspects of the catalytic protocol are necessary for high yields and selectivities providing insight to guide rational optimization of these systems."--Pages v-vi.

Download or read book Multimetallic Catalytic Methods for the Formation of Carbon-carbon Bonds written by Laura Keiko Gilah Ackerman and published by . This book was released on 2016 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This thesis describes the use of multiple transition metal catalysts for the selective formation of carbon-carbon bonds. While the majority of cross coupling reactions rely on one transition-metal catalyst which reacts with a stoichiometric metal reagent, the combination of two metal catalysts in reactions has the potential to significantly increase the expediency towards synthetic targets, eliminating the need for stoichiometric metal reagents and improving functional group compatibility. There are many precedents for the combination of catalysts in organic methodology, however relatively few examples of multimetallic catalyzed reactions exist, and even fewer examples exist where the mechanism between the two catalytic metals is understood. The aim of the projects communicated in this thesis is two-fold: (1) To design new and efficient ways to form useful carbon-carbon bonds (Csp2-Csp3, Csp2-Csp2, and Csp2-Csp2) from readily available starting materials and (2) to provide insight into how two transition metal catalysts can cooperate in a reaction to achieve high selectivity and yield. Chapter 1 reviews the importance of carbon-carbon bond formation and introduces the main methods of cross coupling, including the concept of multimetallic catalysis. Previous examples of dual metal catalysis are summarized in the literature and the advantages and challenges of using two metals in a catalytic system are discussed. Chapter 2 presents a nickel and cobalt catalyzed strategy for the formation of Csp2-Csp3 bonds. The first attempted cross electrophile couplings to form diarylmethanes from benzyl halides and aryl iodides is reported in moderate selectivity, followed by the strategic optimization of the co-catalytic system which enables higher yields and selectivity through the coupling of benzyl sulfonate esters with aryl halides. In this reaction, nickel reacts selectively with aryl halides through an oxidative addition step, while cobalt phthalocyanine generates radicals through an Sn2 reaction with benzyl sulfonate esters, followed by homolysis. The extension of this method to coupling benzyl phosphonate esters and primary and secondary benzyl chlorides is also presented. Chapter 3 reports the quest for and ultimate discovery of a multimetallic catalyzed Csp2-Csp2 coupling. Beginning with stoichiometric transmetalation studies for the coupling of aryl C-H bonds with aryl C-X bonds, the reaction of various metal aryl complexes based on iridium, ruthenium, copper, nickel, and palladium are described. While these reactions were ineffective in generating unsymmetrical biaryls, the catalytic combination of a nickel and palladium catalyst to couple aryl bromides with aryl trifluoromethanesulfonate esters for the design of a cross Ullman reaction was a success. This reaction provided access to a variety of unsymmetrical biaryls maintaining an equimolar catalyst loading of the two metals, and showed promise for later development of the formation of useful unsymmetrical bipyridines and dienes. The scope of this remarkable reaction, the origin of selectivity, and the enhancement in rate and selectivity by a KF additive is presented. Additionally, the optimization strategy towards coupling chlorobenzene and electron-rich aryl chlorides is communicated. Finally, this chapter includes the first attempted multimetallic catalyzed multicomponent reactions with the nickel and palladium as well as nickel and cobalt catalyzed systems, including carbonylation, and the difunctionalization of olefins and alkynes."--Pages xii-xiii.

Book excerpt: In 1972, a very powerful catalytic cycle for carbon-carbon bond formation was 2 first discovered by the coupling reaction of Grignard reagents at the sp -carbon. Over the past 30 years, the protocol has been substantially improved and expanded to other coupling reactions of Li,B,N,O,Al,Si,P,S,Cu,Mn,Zn,In,Sn, and Hg compounds. These reactions provided an indispensable and simple methodology for preparative organic chemists. Due to the simplicity and rel- bility in the carbon-carbon, carbon-heteroatom, and carbon-metalloid bo- formations,as well as high efficiency of the catalytic process,the reactions have been widely employed by organic chemists in various fields. Application of the protocol ranges from various syntheses of complex natural products to the preparation of biologically relevant molecules including drugs, and of sup- molecules, and to functional materials. The reactions on solid surfaces allow robot synthesis and combinatorial synthesis. Now, many organic chemists do not hesitate to use transition metal complexes for the transformation of org- ic molecules. Indeed, innumerable organic syntheses have been realized by the catalyzed reactions of transition metal complexes that are not achievable by t- ditional synthetic methods. Among these, the metal-catalyzed cross-coupling reactions have undoubtedly contributed greatly to the development of such a new area of “metal-catalyzed organic syntheses”. An excellent monograph for the cross-coupling reactions and other met- catalyzed C-C bond-forming reactions recently appeared in Metal-catalyzed Cross-coupling Reactions (Wiley-VCH,1998).

This book was released on 2013-07-03 with total page 1 pages. Available in PDF, EPUB and Kindle. Book excerpt: Transition metal-catalyzed coupling reactions have a rich history that led to the awarding of the 2010 Nobel Prize in Chemistry to Professors Suzuki, Heck, and Negishi for their pioneering contributions to the field. The coming of age of this active area of research is showcased in this book through case studies in which process chemists from the pharmaceutical industry share their personal experiences developing their own transition metal-catalyzed couplings for the large-scale manufacture of active pharmaceutical ingredients. Authors from Pfizer, Merck, Boehringer-Ingelheim, Novartis, Amgen, GSK, AstraZeneca, and other companies describe the evolution of robust coupling processes from inception through early and late development, including commercial routes where applicable. This book covers a wide range of coupling transformations while capturing the lessons learned from each process. Every case study details the optimization of at least one transition metal-catalyzed coupling while elaborating on issues such as design of experiments, scalability and throughput, product purification, process safety, and waste management. The important issue of metal removal and the different technologies available to accomplish this goal are also addressed. Finally, a section covers novel technologies for cross-coupling with high potential for future applications on a large scale, such as microwave and flow chemistry as well as green cross-couplings performed in water.

Available in PDF, EPUB and Kindle. Book excerpt: Transition metal catalyzed cross-coupling reactions have become a staple of organic synthesis and are frequently the most practical strategy for the preparation of medicinal agents and fine chemicals. Catalysts based on the precious metal palladium are commonly used in cross-coupling reactions. Replacing palladium catalysts with nickel catalysts is an active area of research as such advances present significant benefits including increasing the sustainability of transformations and new mechanisms for control of stereochemistry in the construction of Csp-Csp3 bonds. In Chapter 1, a stereospecific nickel-catalyzed cross-coupling reaction of secondary benzylic ethers with a variety of aliphatic and aryl Grignard reagents is presented. The method is highly stereospecific and proceeds with inversion at the benzylic carbon. Products prepared by this method were subject to biological testing, and a thiophene-containing product was shown to selectively inhibit the growth of MCF-7 breast cancer cells. In Chapter 2, mechanistic studies that provide insight into the mechanism of oxidative addition as well as the mechanisms of major side reactions, hydrogenolysis and Îø-hydride elimination, are presented. Experiments presented provide evidence that the mechanisms of cross-coupling, hydrogenolysis, and B-hydride elimination reactions all include a step of oxidative addition with inversion at the benzylic center. Hydrogenolysis was also shown to be stereospecific, proceeding with overall inversion at the stereogenic center. In Chapter 3, the application of nickel-catalyzed cross-coupling reactions to the synthesis of either enantiomer of a bioactive triaryl methane from a single enantiomer of a precursor alcohol is presented. In the key cross-coupling step a Kumada protocol allows for cross-coupling with inversion at the benzylic carbon, while a Suzuki reaction allows for cross-coupling with retention.
