摘要
Abstract
2,3-Dihydro-1H-imidazo[4,5-b]pyridin-2-one(1)was synthesized by ring-closing reaction using 2,3-diaminopyridine as primary material. A novel compound 1,3,5-trinitro-2,3-dihydro-1H-imidazo-[4,5-b]pyridin-2-one(2)was obtained with it by nitration in the system of HNO3/Ac2O,with a yield of 44.6%. Their structures were characterized by 1H NMR,MS and IR,and thermal behavior of compound 2 was studied by differential scanning calorimetry and thermogravimetry. Results show decomposi-tion temperature of compound 2 is 153. 0 ℃,and the mass loss due to overall reaction(130 ~450 ℃)is 55. 5%,indicating poor heat stability of compound 2.关键词
