Visible‐Light‐Mediated Synthesis of Aryl Ketones and Aldehydes from N‐(acyloxy)phthalimides Esters

Abstract

A visible‐light‐mediated decarboxylative oxidation of benzylic redox active esters is described. A diverse array of aromatic ketones or aldehydes could be achieved (15 examples) from secondary or primary aliphatic carboxylic acids. A mechanism involving resonance transformation in the presence of Cs2CO3 is proposed.
