The half-potential of 35 quaternary phosphonium salts with one or more hetero-atoms attached to phosphorus are reported, and the fission products determined for the electroreduction of nine phosphonium salts.The influence of the ligands attached to phosphorus by hetero-atoms on both the half-wave potential and the course of the fission reaction is discussed.The order of precedence in the cleavage of the ligands at phosphorus is examined to determine whether a meaningful, qualitative order of stability for the corresponding ligands as free radicals can be deduced.
