Abstract

Redox systems involving R2P-, R2P(X)-, and R3P+-substituted benzenes and biphenyls (R = Me, Ph) have been studied by cyclic voltammetry in DMF. The first one-electron redn. is reversible in several instances, and stable radical anions, cations, and uncharged radicals were detected by high-resoln. ESR. The second redn. step is irreversible in all cases investigated. The electrochem. and spectroscopic data illustrate the considerable difference in acceptor strength between R2P and R3P+ substituents; MO calcns. of the radical species give a quant. measure of this difference and of the overall substituent effects. A comparison is made between the organophosphorus redox systems presented and the quinone/hydroquinone redox systems. on SciFinder(R)
