Synthesis of 7-Azidoacetamido-4,6-Dinitro-Benzofuroxan

7-Azidoacetamido-4,6-dinitro-benzofuroxan has been synthesized from the starting materials of chloroacetyl chloride and m-chloroaniline, and has been characterized by elemental analysis, IR, 1H NMR and MS spectroscopies. The title compound was obtained through the reactions of amidation, nitration, azidation and pyrolysis. Azido group was introduced into benzofuroxan derivative to give the energetic compound of high nitrogen content and high enthalpy of formation. It is hopeful that the title compound can be developed into new energetic material and energetic plastic additives.
