of phosphoranyl radicals with the general structure (RO)2P(X)OṖ(OR)3(X = O or S) have been studied in solution using e.s.r. spectroscopy. The phosphoranyl radicals were produced by addition of photochemically generated t-butoxyl radicals to (RO)2P(X)OP(OR)2(X = O or S) or diethoxyphosphoryloxyl radicals (EtO)2P(O)O to (RO)3P (X = O). The e.s.r. spectra of these phosphoranyl radicals are consistent with
