preparation of a range of N-substituted phosphoramidohydrazides, hydrazones, and azides is described. NN′-Dibenzylphosphorodiamidic azide is comparatively stable: at 180–200° pyrolysis occurred to give a mixture of products; in boiling decane NN′-dibenzylphosphenimidic amide was formed; the latter also resulted from attempted insertion reactions with boiling o-xylene and piperidine. The azide was unchanged by

The synthesis of a series of novel N-symmetrical and unsymmetrical pyrophosphoramides is described, and their i.r., n.m.r., and mass spectra are discussed. The hydrolysis of the pyrophosphoramides and their reactions with other nucleophilic reagents have been investigated.
