Photoredox generation of the trifluoromethyl radical from borate complexes <i>via</i> single electron reduction

Abstract

A method for the generation of the CF₃ radical from CF₃-substituted borate complexes bearing a pyridine-N-oxide ligand is described. Cleavage of the C-B bond occurs via single electron reduction by a Cu(i) photocatalyst activated by visible light.
