P-(Diphenylphosphino) benzoyl azide (IIa) and diphenylphosphinoacetyl azide (IIb) are prepared by the action of NaNO2 and HCl on the corresponding acid hydrazides (I). The azides (II) are subjected to both base and acid-catalyzed decompositions. II reacts with hydrazine hydrate to give the precursor acid hydrazides (I). The reaction of (II) with benzylamine affords the corresponding amides (III). When (II) is allowed to react with anhydrous AlCl3 in benzene, toluene or anisole, the corresponding amilides (IV) are obtained. The structures of the products are discussed in the light of their chemical and spectroscopic properties.
