The development of benzyltriphenylphosphonium salts as alkyl radical precursors using photoredox catalysis is described. Depending on substituents, the benzylic radicals may couple to form C–C bonds or abstract a hydrogen atom to form C–H bonds. A natural product, brittonin A, was also synthesized using this method.
