Aqueous Organometallic Catalysis 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.
