Book Description
P-stereogenic ligands were among the first to be used in asymmetric catalysis but synthetic difficulties and prejudices have hampered their development. However, continuous screening for new chiral ligands means that they can no longer be ignored and this rigorous reference source reflects their renaissance.The book is filled with many examples from recent primary literature. The synthetic chemist will easily be able to follow the preparation methods which are accompanied by a description of the challenges and limitations. Those working in homogenous catalysis, and wanting to increase their repertoire of ligands, will be able to establish which have already been used in each reaction and their performance.This book provides comprehensive coverage of the application of P-stereogenic ligands in homogeneous catalysis. It begins with a brief chapter on generalities of P-stereogenic compounds: history, configurational stability, and interconversions among them.The book then goes on to describe the main preparative methods, from resolution of racemates to enantioselective catalysis, before focusing on the catalytic applications of P-stereogenic ligands. Chapter 7 describes the use of the ligands in catalytic hydrogenation and related reactions whereas chapter 8 deals with other reactions, mainly C-C bond forming reactions. The aim of these two final chapters is to give an outline of the usefulness of the ligands in homogeneous catalysis.

Book Description
Over the past 20 years aqueous organometallic catalysis has found applications in small- scale organic synthesis in the laboratory, as well as in the industrial production of chemicals with a combined output close to one million tons per year. Aqueous/organic two-phase reactions allow easy product-catalyst separation and full catalyst recovery which mean clear benefits not only in economic but also in environmental and green chemistry contexts. Instead of putting together a series of expert reviews of specialized fields, this book attempts to give a comprehensive yet comprehensible description of the various catalytic transformations in aqueous systems as seen by an author who has been working on aqueous organometallic catalysis since its origin. Emphasis is put on the discussion of differences between related non-aqueous and aqueous processes due to the presence of water. The book will be of interest to experts and students working in catalysis, inorganic chemistry or organic synthesis, and may serve as a basis for advanced courses.

Book Description
This book, unique in its field, is a comprehensive description of all the methodologies reported for carrying out conjugate addition reactions in a stereoselective way, using small chiral organic molecules as catalysts (organocatalysts). In the last 3-4 years, this has been a rapidly growing field in organic chemistry, and many papers have appeared reporting excellent protocols for carrying out these highly efficient transformations that compete well with other classical approachse using transition metal catalysts. A particularly attractive feature of this transformation relies upon the fact that the conjugate addition (Michael and Hetero-Michael reactions) is an extraoridinarily effective means to initiate cascade processes which result in the formation of complex molecules from very small and simple starting blocks. The book, written by noted experts, covers all recent advances in this not topic, and provides a good state-of-the-art review for organic chemists working in this field and all those who wish to start projects in this area. The Series is intended to provide an accessible reference for postgraduates and industrialists working in the field of catalysis and its applications. Books will be produced either as monographs or reference handbooks. The Series will cover research developments and applications of catalysis, in both academia and industry.
