Photoinduced ligand-to-copper charge transfer for decarboxylative hydrogenation of aromatic carboxylic acids

Abstract

A novel ligand-to-metal charge transfer (LMCT)-based synthetic methodology is presented for the decarboxylative hydrogenation of aromatic carboxylic acids. This approach features mild reaction conditions, economical copper-mediated catalysis, and exceptional functional group tolerance. The study addresses significant challenges in aromatic carboxylic acid transformations and underscores the potential of photochemical copper catalysis in contemporary organic synthesis.
