This book was released on 2019 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: C-H borylation (CHB) is a method to functionalize C-H bonds. The development of CHB has taken many years but is getting to the point of well-established chemistry. The directed CHB is possible for a variety of differing substrates and differing loctions of direction. A new method for ortho directed CHB of esters amides and ketones was developed through the use of pyridine based monodentate ligands.Using 4-cyano-2-methoxypyridine as a ligand iridium catalyzed CHB of esters ketones and amides were performed. The mechanism of CHB in this process likely operates through a different rate-determining step than the other C-H borylation methods used as it was found that the kinetic isotope effect data did not clearly support C-H activation as rate-determining.The development of sp3 C-H borylation is not as advanced as sp2 CHB; a 2-step process to generate the same products could be equally desirable. Utilizing a borylation-hydrogenation process the selectivity that have already been developed for sp2 C-H borylation can be used to generate the sp3 carbon boron bond at the desired location. This process has been developed and limitations of it have been investigated.

Download or read book Synthesis of Functionalized Organoboron Compounds Through Copper I Catalysis written by Koji Kubota and published by Springer. This book was released on 2017-06-27 with total page 222 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes state-of-the-art borylation chemistry using copper(I) catalysis. Enantioselective reactions are included to afford a variety of functionalized, complex organoboronate esters, which will find wide application in asymmetric synthesis, drug discovery, and material science. Organoboron compounds are recognized as useful reagents in organic synthesis; therefore, great effort has been devoted to the development of a simple, mild, and efficient method for their preparation in the past several years. However, the synthesis of functionalized organoboron compounds remains a challenging issue because known reactions often require the use of highly reactive organometallic carbon nucleophiles. This book focuses on conceptually new, formal nucleophilic copper(I)-catalyzed borylation reactions with diboron compounds that show high selectivity and excellent functional group compatibility. Theoretical studies based on density functional theory calculations to understand the reaction mechanisms have also been described. Advances in this novel borylation chemistry will allow the rapid and efficient synthesis of complex molecules with potentially interesting properties in combination with the boron functionalization process.

Starting with an introduction to the structure, properties, and preparation of boronic acid derivatives, together with an overview of their reactions and applications, the book goes on to look at metal-catalyzed borylation of alkanes and arenas, coupling reactions and rhodium-catalyzed additions of boronic acids to alkenes and carbonyl compounds. There follows chapters on copper-promoted C-O and C-N cross-coupling of boronic acids, recent applications in organic synthesis, as well as alpha-haloalkylboronic esters in asymmetric synthesis. Later sections deal with cycloadditions, organoboronic acids, oxazaborolidines as asymmetric inducers, and boronic acid based receptors and sensors. The whole is rounded off with experimental procedures, making this invaluable reading for organic, catalytic and medicinal chemists, as well as those working in organometallics.

Download or read book Organometallic Chemistry written by E W Abel and published by Royal Society of Chemistry. This book was released on 2007-10-31 with total page 516 pages. Available in PDF, EPUB and Kindle. Book excerpt: Organometallic chemistry is an interdisciplinary science which continues to grow at a rapid pace. Although there is continued interest in synthetic and structural studies the last decade has seen a growing interest in the potential of organometallic chemistry to provide answers to problems in catalysis synthetic organic chemistry and also in the development of new materials. This Specialist Periodical Report aims to reflect these current interests reviewing progress in theoretical organometallic chemistry, main group chemistry, the lanthanides and all aspects of transition metal chemistry. Specialist Periodical Reports provide systematic and detailed review coverage of progress in the major areas of chemical research. Written by experts in their specialist fields the series creates a unique service for the active research chemist, supplying regular critical in-depth accounts of progress in particular areas of chemistry. For over 80 years the Royal Society of Chemistry and its predecessor, the Chemical Society, have been publishing reports charting developments in chemistry, which originally took the form of Annual Reports. However, by 1967 the whole spectrum of chemistry could no longer be contained within one volume and the series Specialist Periodical Reports was born. The Annual Reports themselves still existed but were divided into two, and subsequently three, volumes covering Inorganic, Organic and Physical Chemistry. For more general coverage of the highlights in chemistry they remain a 'must'. Since that time the SPR series has altered according to the fluctuating degree of activity in various fields of chemistry. Some titles have remained unchanged, while others have altered their emphasis along with their titles; some have been combined under a new name whereas others have had to be discontinued. The current list of Specialist Periodical Reports can be seen on the inside flap of this volume.
