Fine Chemicals Through Heterogeneous Catalysis

Nowadays, the chemical industry is under increased pressure to develop cleaner production processes and technologies. Much effort is devoted to the development of heterogeneous catalysts and their application in industrial-scale organic synthesis. This handbook concentrates on current attempts, focusing on fine chemical production. With contributions from an impressive array of international experts, this is essential reading for everyone interested in the advances in this field.

Heterogeneous catalysis plays a major role in the organic synthesis of specialty and fine chemicals. However, as the interaction between surface sites and functional groups is complex, more investigations are necessary into the effects of catalysts on the reaction mechanisms. The Third International Symposium on Heterogeneous Catalysis and Fine Chemicals provided an opportunity for discussions on the basic and practical aspects of this subject between researchers, manufacturers and users of solid catalysts for synthesis of fine chemicals. The present volume comprises the invited plenary lectures and research papers classified under the three main headings, hydrogenation, oxidation and acid-catalysis. All papers were refereed. A large variety of reactions are described, the emphasis being on selectivity, taking into account all aspects: chemo-, regio-, and stereoselectivity (including enantioselectivity) and on the change of these selectivities as a function of the characteristics of the catalysts and operating conditions.

The recession in the traditional heavy industries along with the development of advanced technologies in all the industrial countries has meant that the impact of heterogeneous catalysis in the synthesis of fine chemicals is becoming increasingly noticeable. The first International Symposium on Heterogeneous Catalysis and Fine Chemicals is to be seen in this perspective. Organised by the Laboratory of Catalysis in Organic Chemistry of the University of Poitiers within the framework of the International Symposia of the `Centre National de la Recherche Scientifique' (CNRS), the symposium provided an opportunity for contact between academic researchers and manufacturers, users (or potential users) of solid catalysts for fine chemical synthesis. Two panels of industrial and academic researchers - one on selective hydrogenation, the other on selective synthesis of substituted aromatics - showed that heterogeneous catalysis already plays a significant role in fine organic chemistry. The main topics of the symposium were introduced in six plenary lectures and three invited communications, maintaining a balance between the industrial and the academic points of view. Some 60 research papers were submitted from which the Scientific Committee selected the 35 communications (oral or poster) which fitted most closely the theme of the symposium. All are reproduced in full in this Proceedings volume.

This book describes the development of two kinds of continuous-flow transformation using heterogeneous catalysts, and explains how they can be applied in the multistep synthesis of active pharmaceutical ingredients. It demonstrates and proves that fine chemicals can be synthesized under continuous-flow conditions using heterogeneous catalysis alone. Importantly, the book also proposes a general concept and strategy for achieving multistep flow synthesis and developing heterogeneous catalysts, and shows that commercially available anion exchange resin can be used as a water-tolerant strong base catalyst for various types of continuous-flow aldol-type reaction. Reviewing the state of the art in heterogeneous catalysis in flow chemistry – a “hot topic” and rapidly developing area of organic synthesis – the book will provide readers with a deeper understanding of fine chemical flow synthesis and its future prospects.

The recession in the traditional heavy industries along with the development of advanced technologies in all the industrial countries has meant that the impact of heterogeneous catalysis in the synthesis of fine chemicals is becoming increasingly noticeable. The second International Symposium on Heterogeneous Catalysis and Fine Chemicals is to be seen in this perspective. Organised by the Laboratory of Catalysis in Organic Chemistry of the University of Poitiers within the framework of the International Symposia of the `Centre National de la Recherche Scientifique' (CNRS), the symposium provided an opportunity for contact between academic researchers and manufacturers, users (or potential users) of solid catalysts for fine chemical synthesis. The book gives an overall view of the problems encountered by academic and industrial researchers. A large variety of reactions are described, the emphasis being on selectivity: chemo-, regio-, stereoselectivity (even enantioselectivity) and on the change of these selectivities as a function of the characteristics of the surface sites (nature, distribution, etc.). The three themes of the symposium, hydrogenation, oxidation and acid-base catalysis were introduced in four plenary lectures and two invited communications, maintaining a balance between the industrial and the academic points of view. Some 60 research papers selected by the Scientific Committee were presented. All are reproduced in full in this proceedings volume.

This book examines the latest research and discovery in the use of MOFs in catalysis, highlighting the extent to which these materials have been embraced by the community.

As the broad challenges around energy and the environment have become the focus of much research, scientists and experts have dedicated their efforts to developing more active and selective catalytic systems for key chemical transformations. For many decades environmentally viable protocols for the synthesis of fine chemicals have been the crux of academic and industrial research. Heterogeneous Catalysis in Organic Transformations serves as an overview of this work, providing a complete description of role of heterogeneous catalysis in organic transformations and offering a review of the current and near future technologies and applications. Discusses the fundamentals of catalysis and compares the advantages and disadvantages of different types of catalyst systems Examines oxide nanoparticles and noble metal nanoparticles Consider organometallic compounds, solid-supported catalysts, and mesoporous materials Describes recent advances in metal-based heterogeneous catalysts and new reactions with possible mechanistic pathways Providing a comprehensive review of heterogeneous catalysis from the basics through recent advances, this book will be of keen interest to undergraduates, graduates, and researchers in chemistry, chemical engineering, and associated fields.
