The reaction between diazodiarylmethanes and triphenylphosphine has previously been shown to be an elementary biphilic reaction in which each reactant behaves simultaneously as both electrophile and nucleophile.Frontier molecular orbital considerations pr
Organic Reactive Intermediates: Part IX-Radical Ions as Reactive Intermediates in Redox Reactions of Triphenylphosphazines

Two representative phosphazines namely, fluorenylidenetriphenylphosphazine (1) and diphenylmethylenetriphenylphosphazine (2) are shown to undergo oxidation and reduction involving single electron transfer to yield the corresponding cation and anion radicals, respectively.These ion radicals are unstable and decompose to give rise to a blend of other intermediates.Those which act almost certainly as principal intermediates in oxidation and reduction are carbenes and diazoalkane radical anions respectively.
