Visible-light-induced Synthesis of Organic Peroxides via Decarboxylative Couplings of Carboxylic Acids, Alkenes and tert-Butyl Hydroperoxide
摘要
Herein, we present a photoinduced, CeCl3-catalyzed three-component decarboxylative reaction that couples carboxylic acids, alkenes and tert-butyl hydroperoxide for the formation of various organic peroxides. The ligand-to-metal charge transfer (LMCT) excitation mode allows the decarboxylative alkylation-peroxidation reaction to occur under mild conditions, and is well applicable to primary, secondary and tertiary carboxylic acids and styrene derivatives.
