几个2,5-三烷氧基-4-硝基-N,N-二甲苯胺的合成
Synthesis of several 2,5-dialkoxy-4-nitro-N,N-dimethyl-benzenamines
【摘要】 以六甲基磷酰三胺(HMPA)为介质,在140℃二甲胺(由直接加入反应体系中的二甲胺盐酸盐和碳酸氢钠反应产生)和相应的涣苯发生亲核取代反应,即可得2,5-二烷氧基(甲氧基、乙氧基和丁氧基)-4-硝基-N,N-二甲苯胺。
【Abstract】 Three 2,5-dialkoxy-4-nitro-N, N-dimethyl-benzenamines(1~3)were synthesized by nucleophilic substitution of the corresponding bromobenzenes with dimethylamine in HMPA at 140℃. Nucleophilic dimethylamine used in these substitution courses was generated by dimethylamine hydrochloride and sodium bicarbonate added directly into the reaction systems.
