摘 要:以乙二醛、苯肼和盐酸羟胺为起始原料,经缩合、肟化,生成中间体肟基苯腙,加入硫酸铜-吡啶-水体系,缩合环化得到2-苯基三唑-1-氧化物(PTO),然后硝硫混酸硝化合成了2-(3,5-二硝基苯)-4-硝基三唑-1-氧化物(TNPTO),总收率45%,中间体和TNPTO均通过红外光谱、核磁、质谱以及元素分析等进行了结构表征。初步探讨了铜盐作用下合成三唑环的反应机理。 |

Abstract:Starting from glyoxal,phenylhydrazine and hydrochloride hydroxylamine,2-(3,5-dinitrophenyl)-4-nitro-1,2,3-triazole-1-oxide(TNPTO)was synthesized by the processes of condensation,oximation,cyclization and nitration in overall yield of 45% and purity of 99%. The target compound and its intermediates were characterized with IR,1H NMR and elemental analysis. The reaction mechanism of cyclization in the solution of cupric sulphate-pyridine-water was proposed. |
