Abstract

Abstract : Photo-induced radical reductive dehalogenation of inactivated aryl/alkyl bromides and chlorides with a palladium complex is described. Reductive cyclization, dehalogenative deuteration, and radical addition process can be achieved smoothly. Abstract : Herein, a novel photo-induced amine-free radical reductive dehalogenation of inactivated aryl/alkyl bromides and chlorides with a palladium complex is described, which reveals excellent functional group compatibility and broad substrate scope. Extensional transformations for reductive cyclization, dehalogenative deuteration, and intra- and intermolecular radical addition can be achieved smoothly. Mechanistic studies indicate a single-electron photoredox catalytic system with inactivated solvent as the hydrogen atom donor.
