New Method for Synthesis of 7-Amino-4,6-Dinitro-Benzofuroxan

摘要：

An insensitive explosive, 7-amino-4,6-dinitro- benzofuroxan, was synthesized via condensation, nitration, azidation-denitrogenation and hydrolysis from the starting materials of m-chloroaniline, with the yields of 95.4％, 82.0％, 84.0％ and 85.5％ respectively. In the first reaction, amino group was protected with chloroacetylation. The conditions of the synthesis are mild and safe. The pyrolysis of denitrogenation after azidation in one pot took place at 80C, and all the other reactions proceeded at room temperature. The title compound was analyseded by means of H NMR, IR, MS, and elemental analysis.
