E=SAs>Sb. These reactivities are parallel with the electrochemical oxidation potentials reported for Ph2E and with the first ionization potentials reported for Ph3M. The rate of Φ2Te was faster than that of Ph3P and slightly faster than that of Φ3Sb. From the reactivity of [Φ2E-Me]+ salts with nucleophiles, the E+–Me bond strengths were estimated to increase in the order E=Se
