摘 要:以乙二醛、苯肼和鹽酸羥胺為起始原料,經(jīng)縮合、肟化,生成中間體肟基苯腙,加入硫酸銅-吡啶-水體系,縮合環(huán)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),總收率45%,中間體和TNPTO均通過(guò)紅外光譜、核磁、質(zhì)譜以及元素分析等進(jìn)行了結構表征。初步探討了銅鹽作用下合成三唑環(huán)的反應機理。 |

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. |
