Tungsten Promoted Decarboxylative Oxygenation and Ring-Opening via Ligand-to-Metal Charge Transfer

Abstract

A decarboxylative oxidation and ring-opening protocol of carboxylic acids via tungsten-catalyzed photoinduced ligand-to-metal charge transfer (LMCT) is described. This reaction enables the preparation of carbonyl and 1,n-dicarbonyl compounds. To the best of our knowledge, this is the first example of the tungsten catalyzed decarboxylative functionalization reactions.
