Following on from Volume 2, a separate section covers Friedel-Crafts alkylation reactions, which is complemented by discussions of polyene cyclizations and electrophilic transannular cyclizations in synthesis. Coupling reactions leading to &agr;-bond formation, and involving all types of combinations ofsp3, sp2 and sp carbon centers are next covered, including those reactions based on pinacol, acyloin and phenol oxidative coupling reactions, and also the Kolbe reaction. Rearrangement reactions, leading to carbon-to-carbon &agr;-bond formation, are often used in a clever manner in synthesis. The volume includes all those rearrangement reactions based on intermediate carbonium ions and carbanions, and also includes the benzil-benzilic acid and the Wolff rearrangements. The volume closes with coverage of carbonylation reactions, and the use of carbene insertion reactions into the C-H bond in synthesis.

Book Synopsis The Chemistry of Carbon by : A. K. Holliday
Download or read book The Chemistry of Carbon written by A. K. Holliday and published by Elsevier. This book was released on 2013-10-22 with total page 167 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Chemistry of Carbon: Organometallic Chemistry is a specialist's selection of certain chapters in Comprehensive Inorganic Chemistry comprising five volumes. This book contains corrections and added prefatory material and individual indices. This volume deals with carbon (Chapter 13) and describes organic chemistry of the metallic elements (Chapter 14). Carbon is unique in its ability to form strong chemical bonds with itself or other elements. Graphite and diamonds are some elementary forms of carbon. Chapter 14 discusses the basis for a qualitative, comparative description of the organic chemistry of metals and any inorganic chemistry found common in them. The book uses the covalent model in describing both bondings made in most organometallic compounds and inorganic derivatives. The text also discusses the atoms in molecules, particularly in a molecular ion, as having both ligands X and a central atom M. A table then shows the classification of some common ligands, grouping them according to the number of valence electrons that make up their bonding. The text then explains the general trends in the chemistry of the main group elements of the Periodic Table that contain ns and np orbitals in their valence shells. The book also discusses some atomic properties, their consequences, and the occurrence of unpaired electrons in organo transition metal complexes. This book will be valuable for students and professors dealing with general chemistry, gemologists, molecular scientists, and researchers.

Book Synopsis Catalytic Methods for Carbon-carbon and Carbon-nitrogen Bond Formation by : Stephen David Ramgren
Download or read book Catalytic Methods for Carbon-carbon and Carbon-nitrogen Bond Formation written by Stephen David Ramgren and published by . This book was released on 2014 with total page 511 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation describes the study of metal-catalyzed cross-coupling reactions to construct carbon-carbon and carbon-heteroatom bonds. The key feature of much of this work is the use of inexpensive Ni and Fe catalysts to enable the coupling of unconventional electrophilic substrates, specifically aryl O-sulfamates and O-carbamates. The ability to use O-sulfamates and O-carbamates in catalytic processes is notable, as these substrates are readily derived from phenols and can be used for directed arene functionalization. Chapter one provides a summary of the efforts towards using alcohol-based solvents for the Suzuki-Miyaura cross-coupling reaction. Emphasis is placed on the cross-coupling of heterocycles, which are commonly encountered in natural product synthesis and in the pharmaceutical sector. Chapters two, three, and four describe carbon-nitrogen bond forming reactions. Chapter two pertains to the nickel-catalyzed amination of sulfamates, which culminated in the synthesis of the antibacterial drug, linezolid. Chapter three covers the amination of aryl O-carbamates and their use in sequential functionalization/site-selective cross-couplings. Chapter four describes a more user-friendly variant of the amination reaction, which relies on a bench-stable Ni(II) precatalyst, rather than a more commonly used Ni(0) precatalyst. Chapters five, six, and seven focus on carbon-carbon bond formation via Fe-, Ni- and Pd-mediated processes. Chapter five pertains to iron-catalyzed couplings of sulfamates and carbamates to generate sp2-sp3 carbon-carbon bonds. This method can be used to assemble sterically-congested frameworks. Chapter six describes the nickel-catalyzed Suzuki-Miyaura reactions of halides and phenol derivatives in `green' solvents, which was applied to the preparative scale assembly of bis(heterocycles) using low nickel catalyst loadings. Chapter seven pertains to the acetylation of arenes using palladium catalysis, which provides a simple and efficient means for the construction of a variety of aryl methyl ketones.

Book Synopsis Advances in Late-Metal Carbon-Nitrogen Bond Formation for the Synthesis of Substituted Heterocycles by : Nicolas Rotta-Loria
Download or read book Advances in Late-Metal Carbon-Nitrogen Bond Formation for the Synthesis of Substituted Heterocycles written by Nicolas Rotta-Loria and published by . This book was released on 2017 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Late-metal catalyzed cross-couplings have emerged as efficient and selective methodologies for the formation of C-C and C-N bonds. The ability to synthesize complex heterocycles from cheap and abundant starting materials is an invaluable asset to the pharmaceutical industry, given that many pharmaceuticals contain at least one heterocyclic component. This reactivity can be achieved by tuning the steric and electronic properties of ancillary ligands to support metal catalysts in the reaction steps leading to the target substrate. The Stradiotto group has developed several state-of-the-art methodologies involving ligands for palladium catalysis, for both C-C and C-N bond-forming reactions. These methodologies can be amalgamated into a multicomponent reaction platform to synthesize more complex products from simple materials. Chapter 1 outlines this concept with the application of a Mor-DalPhos/Pd catalyst in the one-pot synthesis of indoles from acetone and simple amines involving C-C and C-N bond formation. The robust nature of this method can be extended to include benchtop reaction conditions in a one-step, one-pot synthesis of indoles, thus representing a useful synthetic protocol. While palladium provides a powerful tool for C-C and C-N bond formation, the general trend in catalysis has shifted away from the precious metals toward first row metals as economic alternatives. Nickel complexes have recently emerged as excellent catalysts for a number of amination reactions. The ability to utilize ammonia also represents a sought after reaction, due to the widespread availability and synthetic utility of amino-functionalized products. In this regard, Chapter 2 will focus on the development and application of both commercially available and strategically designed ligand classes for the monoarylation of ammonia with substituted heterocycles. Hydrazine represents an important synthon in synthetic chemistry. It is synthesized on multi-ton scale every year and represents an important building block in many industrial processes. Many synthetic challenges arise from using free hydrazine as reactant, which has led to lethargic growth of its application in the field of late-metal catalyzed C-N bond-formation. However, gold-catalyzed methodologies have been developed utilizing NHC ligands to allow for the hydrohydrazination of alkynes with parent hydrazine. Chapter 4 examines the development and application of a series of (PR3)AuCl complexes for use in such transformations, leading to the identification of the first effective phosphine-bound gold complex for use in the hydrohydrazination of alkynes at room temperature.

This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Ru carbene complexes have been investigated for potential application toward carbon-nitrogen bond forming and breaking reactions. The reactivity of Grubbs-type olefin metathesis catalysts (Cl)2(L)(L')Ru=CHPh (L = L' = PCy3 or PPh3; L = PCy3 and L' = H2MesNHC) has been studied with cyclic and acyclic imines. The Ru benzylidene complex (Cl)2(PCy3)2Ru=CHPh undergoes a ligand exchange reaction with 1-pyrroline at room temperature, and oligomerizes 1-pyrroline at 90 oC. The low molecular weight poly(1-pyrroline) has been isolated and characterized. The Ru benzylidene complex has no reactivity toward acyclic imine C=N bonds, but reacts with enamine C=C bonds that form through tautomerization of imines. The Ru amido complexes, (PCP)Ru(CO)(NHPh) and (PCP)Ru(CO)(NHPh)(PMe3) (PCP = 2,6-(CH2P-t-Bu2)C6H3), have been synthesized and characterized. Reaction of (PCP)Ru(CO)(NHPh)(PMe3) with acetonitrile produces the amidinate complex (PCP)Ru(CO)(NHC(Me)NPh). Kinetic studies have demonstrated the formation of the amidinate complex occurs through dissociation of the PMe3 ligand, coordination of MeCN, and intramolecular nucleophilic attack of the amido ligand toward MeCN. The intramolecular nucleophilic attack reaction has been extensively studied with aromatic nitriles, carbodiimides, isocyanates, carboxamides and aldehydes. Reaction of (PCP)Ru(CO)(NHC(Me)NPh) with pentafluorobenzonitrile results in formation of a new amidinate complex (PCP)Ru(CO)(NHC(C6F5)NPh). The complex (PCP)Ru(CO)(NHC(C6F5)NPh) can initiate a C-F bond cleavage reaction of C6F5CN with ortho regioselectivity in the presence of ROH (R = H or Me). Reaction of five-coordinate complex (PCP)Ru(CO)(OTf) (OTf = OSO2CF3) with NaBAr'4 (Ar' = 3,5-(CF3)2C6H3) under different conditions results in formation of [(PCP)Ru(CO)(ClCH2Cl)][BAr'4], [(PCP)Ru(CO)(N2)][BAr'4] or [(PCP)Ru(CO)(FC6H5)][BAr'4]. Calculations have confirmed that the possible four-coordinate Ru complex with double agostic interactions has a higher ground state.

Download or read book Mechanistic Studies on Metal-catalyzed Carbon-nitrogen Bond Forming Reactions written by Eric R. Strieter and published by . This book was released on 2005 with total page 330 pages. Available in PDF, EPUB and Kindle. Book excerpt: (Cont.) A systematic mechanistic analysis of Pd(OAc)2/ monophosphino- biaryl-catalyzed C-N bond forming reactions with aryl chlorides has been performed. The results provide insights into the relationship between the steady-state concentration of active Pd and the size and substitution pattern of the monophosphinobiaryl ligands. These insights into the nature of catalyst activation help highlight the importance of establishing a high concentration of active catalyst. The catalyst derived from the bulkiest ligand in the series, the tri-i-propyl ligand 13, exhibits both accelerated rate and the increased stability required for practical application of this reaction.
