The electron spin resonance spectra of the anion radicals produced by electrochem. reduction of diethyl 4-nitrophenyl phosphate (I), O O-diethyl O-4-nitrophenyl thiophosphate, diethyl 4-nitrobenzyl phosphonate (II), diphenyl 4-nitrophenyl phosphate, diphenyl 2,6-dimethyl-4-nitrophenyl phosphate, bis(4-methylphenyl) 4-nitrophenyl phosphate, and bis(2-methylphenyl) 4-nitrophenyl phosphate have been examined In every case, unequivocal assignment of a 31P hyperfine coupling constant, aP, was possible. The magnitude of aP varied from 7.05 gauss for the radical derived from I in acetonitrile to 17.51 gauss for the radical derived from II in HCONMe2. In all cases, the values of the N and nitrophenyl ring proton coupling constants remained closely similar to those observed for nitrobenzene anion. The variation in values of aP suggests that steric effects as well as inductive effects influence the 31P coupling constant in these radicals and that at least some contribution of a hyperconjugative mechanism is likely for transmission of unpaired spin to the P atom.
