Catalysis is a fundamentally sustainable process which can be used to produce a wide range of chemicals and their intermediates. Focussing on those catalytic processes which offer the most sustainability, this two-part book explores recent developments in this field, as well as examining future challenges. Focussing on catalysis without metals or other endangered elements, each chapter covers a different type of organocatalyst. Beginning with chapters on acid and base catalysis, the book then concentrates on asymmetric catalysis. Several chapters cover pyrrolidine-based and cinchona alkaloid-based catalysts, whilst other chapters examine further organoctalysts which are constructed only from sustainable elements. Together with Sustainable Catalysis: With Non-endangered Metals , these books examine the progress in sustainable catalysis in all areas of chemistry, and are an important reference for researchers working in catalysis and green chemistry.
