PHOTOORGANOCATALYSIS IN ORGANIC SYNTHESIS

The use of organocatalysts able to photocatalyze an organic reaction is a rapidly growing field. These photocatalyzed transformations are more environmentally sustainable with respect to the use of expensive/toxic metal-based (photo)catalysts.Based on the authors' extensive experience in photogenerated intermediates, this book presents an overview on photocatalyzed organic processes having a synthetic significance, where an organic molecule functions as the photocatalyst.After a brief introduction defining the nature and the characteristics of a photoorganocatalyst (POC), the chapters are organized according to the class of POC used, as detailed below. Ketones and aldehydes;Quinones;Aromatics and cyanoaromatics;Sulfur heterocycles;Oxygen heterocycles: pyrylium salts, eosin derivatives, fluorescein, rhodamines, rose bengal;Nitrogen heterocycles: porphyrins, acridinium salts, carbazoles, imides and PDI, mpg-C₃N₄, tetrazines, riboflavin, and BODIPY; Each chapter begins with a summary of the photophysical characteristics of the POCs and is followed by selected examples of synthetic applications. The last two chapters are devoted to the adoption of photoorganocatalysis in polymerization and to flow photoorganocatalysis. These in-depth explanations and practical applications make this title an essential reading for any chemistry student interested in organic (sustainable) synthesis.
