N-heterocyclic carbenes / Silvia Díez González

Public ISBD Titre : N-heterocyclic carbenes : from laboratory curiosities to efficient synthetic tools Type de document : texte imprimé Auteurs : Silvia Díez González, Éditeur scientifique Editeur : Cambridge : RSC Publishing Année de publication : 2011 Importance : xxv, 442 p. Présentation : ill. couv. ill. en coul. Format : 24 cm ISBN/ISSN/EAN : 978-1-84973-042-6 Langues : Anglais (eng) Catégories : Chimie de coordination, Chimie organométallique, Métaux de transition Tags : CARBENES  HETEROCYCLIC CHEMISTRY Index. décimale : B-D Résumé : "Over the last fifteen years, N-heterocyclic carbenes (NHCs) have mostly been used as ancillary ligands for the preparation of transition metal-based catalysts. Compared to phosphorus-containing ligands, NHCs tend to bind more strongly to metal centres, avoiding the necessity for the use of excess ligand in catalytic reactions. The corresponding complexes are often less sensitive to air and moisture, and have proven remarkably resistant to oxidation. Recent developments in catalysis applications have been facilitated by the availability of carbenes stable enough to be bottled, particularly for their use as organocatalysts. This book shows how N-heterocyclic carbenes can be useful in various fields of chemistry and not merely laboratory curiosities or simple phosphine mimics. NHCs are best known for their contribution to ruthenium and palladium-catalysed reactions but the scope of this book is much broader. The synthesis of NHC ligands and their corresponding metal complexes are covered in depth. Moreover, the biological activity of NHC-containing complexes, as well as an overview of their theoretical aspects are included. Such metal species are further examined, not only in terms of their catalytic applications, but also of their stereoelectronic parameters and reactivity/stability. Finally, special attention is given to the hot topic of organocatalysis. The book will be of interest to postgraduates, academic researchers and those working in industry."

Advances in Carbene Chemistry. Vol. 2 / Udo H. Brinker

Public ISBD Titre : Advances in Carbene Chemistry. Vol. 2 Type de document : texte imprimé Auteurs : Udo H. Brinker, Éditeur scientifique Editeur : London [England] : Jai Press Année de publication : 1998 Importance : x, 301 p. ISBN/ISSN/EAN : 978-1-55938-837-5 Langues : Anglais (eng) Tags : CARBENES  ORGANIC-Chemistry Index. décimale : EQ -Equipe- Résumé : "Beginning as chemical curiosities, carbenes are now solidly established as reactive intermediates with fascinating and productive research areas of their own. Five decades of divalent carbon chemistry have provided us with a vast repertoire of new, unusual and surprising reactions. Some of those reactions, once classified as exotic, have become standard methods in organic synthesis. These highly reactive carbene species have been harnessed and put to work to achieve difficult synthetic tasks that other reactive intermediates cannot easily perform. The fruitful relationship between experiment and theory has pushed carbene chemistry further toward the direction of reaction control; that is, regio- and stereoselectivity in intra- and intermolecular addition and insertion reactions. The interplay between experiment and modern spectroscopy has led to the characterisation of many carbenes that are crucial to both an understanding and a further development of this field. Understanding of carbene chemistry has advanced dramatically, especially in the last decade, and new developments continue to emerge. Some of the recent exciting findings have been collected in the first volume of Advances in Carbene Chemistry. With this second volume, the series will continue to provide a periodic coverage of carbene chemistry in its broadest sense - leading into the next century."
