o-Aminophenol reacts with a number of halo- and organophosphazenes in boiling xylene to yield bis-(o-phenyleneoxyamino)-2-aminophenoxyphosphorane (III) and ammonium halide or ammonia. This ring cleavage reaction occurs with (NPCI2)3, (NPCI2)4, (NPCI2)15.000, (NPBr2)3, (NPF2)3, and with certain organocyclotriphospha-zenes which contain a five-membered cyclic side unit attached to phosphorus. No reaction was observed with [NP-(OC6H5)2]3, [NP(OC6H4NO2)2]3, [NP(NHC6H5)2]3, or [NP(O2C12H8)]3. The structural proof for III is described and the complex reaction mechanism is discussed.
