here as a new method to obtain amines from aromatic nitro compounds. Amines are synthetized in a straightforward step and are isolated as hydrochloride salts with good to excellent yields. This system has shown a good selectivity toward aryl-chloride, aryl-bromide, ester, carboxylic acid, and cyano groups. The reduction of alkylnitro compounds was unfortunately not possible using this method, only a mixture
本文报道了系统1,1,3,3-四甲基二硅氧烷(TMDS)/ Fe(acac)3作为从芳族硝基化合物获得胺的新方法。胺可通过简单的步骤进行合成,并以良好或极好的收率分离为盐酸盐形式。该系统显示出对芳基氯化物,芳基溴化物,酯,羧酸和氰基的良好选择性。 不幸的是,使用该方法无法还原烷基硝基化合物,仅获得了单和二烷基化胺的混合物。
