Organometallics in Process Chemistry


Book Description

The design of efficient syntheses of medicinal agents is one of the prime goals of the process chemist in the pharmaceutical industry. The expanding list of metal-mediated reactions has had a major impact on this endeavor over the last two decades. This volume will highlight some of the areas of organometallic chemistry that have played a particularly important role in development. The chapters are written by chemists who work in the process groups of major pharmaceutical companies and fine chemical manufacturers. Having demonstrated the power of organometallics in their processes the authors herein expand upon their experiences with examples from the literature as reported by process groups within the industry. The chapters are organized either by the application of a particular metal or reaction class. Removal of the residual metal(s) from the isolated active pharmaceutical ingredient (API) is key to the release of the material for human consumption, and hence, is reviewed here as well. This volume of Topics in Organometallic Chemistry is presented to offer a representative cross section of organometallic applications in the pharmaceutical industry as well as to give an appreciation for the creativity possible in process chemistry.

Organometallic Mechanisms and Catalysis


Book Description

Organometallic Mechanisms and Catalysis: The Role of Reactive Intermediates in Organic Processes covers the mechanistic delineation of organometallic chemistry and catalysis. This book is organized into three parts encompassing 18 chapters. The first part describes first the oxidation-reduction process of organometals, followed by discussions on the catalytic reactions of peroxides, metal-catalyzed addition to olefins, and reduction of organic halides. This part also explores other reactions involving transition metal carbonyls and metal-catalyzed reactions of aromatic diazonium salts. The second part deals with some chemical aspects of organometals, such as their stability, thermochemistry, decomposition, hemolytic pathways, and the formation of carbon-carbon bonds. The third part examines the charge transfer processes and interactions of organometals with electron acceptors. This part further looks into the cleavage and insertion reactions of organometals with electrophiles, as well as the electrophilic and electron transfer mechanisms of organometals. Organic and inorganic chemists, teachers, and students will greatly benefit from this book.




Aqueous Organometallic 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.
