The possibility of the three-component condensation of hydrazoicacid and formaldehyde with primary or secondary amines, as well as with trialkylhydrazines, leading to the corresponding N-azidomethyl derivatives of amines and hydrazides was established.

nitrogen content, density and enthalpy of formation. Herein, a simple, mild and general procedure has been developed for the preparation of diverse N-(chloromethyl)nitramine building blocks from readily available N-(acetoxymethyl)nitramines via a TiCl4-catalyzed chlorodeacetoxylation with SOCl2. This new protocol allows the conversion of both mono- and di(acetoxymethyl) precursors that contain one to
