Book Description
Immobilization of chiral catalysts is an important tool for improving overall efficiency of catalytic processes. However, heterogeneous catalysts often suffer from decreased activities and supported but still homogeneous catalysts can help overcome this issue. This book covers the most important concepts of homogeneous supported catalysis with an emphasis on enantioselective processes. It describes the state-of-the-art and latest developments in each area whilst critically evaluating the strengths and weaknesses of this important method. The book encompasses ionically-tagged catalysts, supported organocatalysts, supported ionic liquid phases, catalysis using soluble polymers, catalytic dendrimers, fluorous catalysts, water soluble catalysts and non-covalent immobilization methods. Potential developments and ideas for the future are also highlighted. There is a growing demand for effective and recyclable catalysts so this book, covering all the important methods in the field of supported homogeneous catalysis, will appeal to many researchers in academia and industry.

Book Description
It was a great honor for us to organize ChiCat, a symposium devoted to Chiral Reactions in Heterogeneous Catalysis and to be the hostsofmore than 120 scientists coming from everywhere in the industrialized world, to celebrate together one century of existence ofInstitut Meurice. This school was established in 1892when an industrial chemist, named Albert Meurice, decided to educate practical chemists according to the perceived needs ofthe industry ofthat time. This is exactly what we are still trying to do. It is the reason why, thirty years ago, we started a research activity in catalysis, and why we progressively devote this research to the applications of catalysis in the field of fine chemicals. In this respect, we are very close to another initiative of Albert Meurice, who started the first production of synthetic pharmaceuticals in Belgium during World War I. This business later on became a part ofthe Belgian corporation DCB, still very active in pharmaceuticals today. The school created by Albert Meurice merged in the fifties with another school that had been created to meet the same needs in the field of the food industries, mainly distilleries and breweries. This merger was done in the frame of the establishment of CERIA. For people in catalysis, ceria stands for cerium oxide, but for those who engineered the concept, CERIA stood for Center of Education and Research for the Food and Chemical Industries.

Book Description
This publication is the first to present the quantitative application of quantum chemistry to organometallic reactions. Great progress has been made in recent years in the calculation of transition states of organometallic conversions in both homo and heterogeneous catalysis. This volume, which contains seven contributions by leading scientists, deals with key reactions of homogeneous catalysis including oxidative addition, migratory insertions, 2+2 additions, the Wacker reaction, and epoxidation. The book provides experimental chemists with an up-to-date overview of the state of the art in this field, and will stimulate an adjustment of views previously based on semiempirical calculations. For researchers and advanced graduate students whose work involves organometallics and catalysis.

Book Description
The features of this book which will be of special interest to academic organic chemists are the introduction (Chapter 1), which presents a short course on the concepts and language of heterogeneous catalysis, covers organic reaction mechanisms of hydrogenation (Chapter 2), hydrogenolysis (Chapter 4), and oxidation (Chapter 6), a presents problems and solutions specific for running heterogeneous catalytic organic reactions in solution. These materials can supplement advanced chemistry courses. Most synthetic organic chemists use a variety of "protecting groups" which they attach to functional groups (reactive groups of atoms) while some reaction is being conducted on another part of the molecule. These protecting groups prevent reactions of the functional groups during other reactions and are removed later by a heterogeneous catalytic method called hydrogenolysis. One unique feature of this book, not found in other books on catalysis, is an exhaustive chapter (Chapter 4) on hydrogenolysis, which is dredged from the recent synthetic literature published by modern organic chemists. Academic organic chemists should find this chapter extremely useful and may wish to adopt the book as a supplement for advanced organic chemistry courses designed for seniors and for graduate students. It will also be useful for professors and their research groups engaged in synthetic organic chemistry. Many academic organic chemists are not aware of recent advances in heterogeneous enantioselective catalysis (Chapter 3) or in selective low temperature, liquid phase heterogeneous catalytic oxidations by hydrogen peroxide (Chapter 6). These specialty topics are timely and may be new to academic organic chemists and can be used to supplement their advanced courses. Several features of this book will also be of special interest to industrial chemists who are unfamiliar with heterogeneous catalysis. Many good organic chemists are hire by industry. They synthesize a new compound using standard organic synthetic techniques but are informed by their supervisor that they must convert some of their synthetic steps into heterogeneous catalytic steps. They may not have been exposed to heterogeneous catalysis and have few places to turn. This book offers them a crash course in heterogeneous catalysis as well as many examples of reactions and conditions with which they can start their search. Those industrial organic chemists already familiar with heterogeneous catalysis will find this book useful as a reference to many examples in the recent literature. They will find recent surface science discoveries correlated with heterogeneous catalysis or organic reactions and mechanistic suggestions designed to stimulate innovative nontraditional thinking about organic reactions on surfaces. - Written by organic chemists for organic chemists - Introduces heterogeneous catalysis concepts and language - Presents a comprehensive compilation of protecting group removal procedures - Covers liquid-phase hydrogenations, hydrogenolysis, and oxidations - Addresses heterogeneous methods for producing pure enantiomers of chiral products - Examines the emerging field of heterogenized homogeneous catalysts - Mixes practical applications with mechanistic interpretations

Book Description
The need to improve both the efficiency and environmental acceptability of industrial processes is driving the development of heterogeneous catalysts across the chemical industry, including commodity, specialty and fine chemicals and in pharmaceuticals and agrochemicals. Drawing on international research, Supported Catalysts and their Applications discusses aspects of the design, synthesis and application of solid supported reagents and catalysts, including supported reagents for multi-step organic synthesis; selectivity in oxidation catalysis; mesoporous molecular sieve catalysts; and the use of Zeolite Beta in organic reactions. In addition, the two discrete areas of heterogeneous catalysis (inorganic oxide materials and polymer-based catalysts) that were developing in parallel are now shown to be converging, which will be of great benefit to the whole field. Providing a snapshot of the state-of-the-art in this fast-moving field, this book will be welcomed by industrialists and researchers, particularly in the agrochemicals and pharmaceuticals industries.
