Reaction of triphenylphosphine radical cation with cycloalkenes: electrochemical one-step preparation of 1-cycloalkenyltriphenylphosphonium salts

Abstract Constant current electrolysis of triphenylphosphine in dichloromethane at a graphite anode in the presence of cycloalkenes gave the corresponding 1-cycloalkenylphosphonium salts in reasonable yields.
