5-triphenylphosphole with aryl-, arylsulphonyl-, methylsulphonyl-, ethoxycarbonyl-, and diphenylphosphinyl-azides readily give the novel 1,2,5-triphenylphospholimines (I; X = Ar, ArSO2, MeSO2, EtO2C, Ph2PO) which are thermally stable except for N-o-nitroaryl derivatives, e.g.(III), which give benzofurazans and 1,2,5-triphenylphosphole oxide, a reaction which does not occur with the corresponding P-triphenyl-or P-trithoxy-derivatives
1,2,5-三苯基膦与芳基-,芳基磺酰基-,甲基磺酰基-,乙氧基羰基-和二苯基次膦酰基叠氮化物的反应轻松获得了新的1,2,5-三苯基膦酰亚胺(I; X = Ar,ArSO 2,MeSO 2,环氧乙烷2 C,博士2 PO)具有热除了稳定ñ - ö -nitroaryl衍生物,例如(III),这给benzofurazans和1,2,5- triphenylphosphole氧化物,其不与所述相应发生反应P -三苯基-或P -trithoxy衍生物[PH 3 P = NAR或(ETO)3 P = NAR]。
