Visible Light-Induced Decarboxylative Peroxidation of Carboxylic Acids: Metal-Free Synthesis of Benzyl Peroxides

A visible light-induced direct decarboxylative peroxidation of carboxylic acids under mild conditions has been disclosed. With this protocol, a variety of readily available carboxylic acids were converted to the peroxidation products in moderate to good yields via decarboxylative radical C-OO bond coupling. Tert-butyl hydroperoxide acts as both the oxidant and peroxyl source, avoiding the use of transition metals or extra oxidants. A visible light-induced decarboxylative peroxidation of carboxylic acids has been disclosed. With this protocol, a variety of readily available carboxylic acids were converted to the stabilized organic peroxides in moderate to good yields.image
