Abstract Aniline undergoes regioselective trichlorination by N-chlorosuccinimide (NCS) in acetonitrile in good yield. The product 2,4,6-trichoroaniline was converted into 1,3,5-trichlorobenzene by reduction of its diazonium salt. Reaction of the methyl carbamate of aniline with NCS gave only the 2,4-dichlorophenyl carbamate.
摘要 苯胺在乙腈中被 N-氯琥珀酰亚胺 (NCS) 以良好的收率进行区域选择性三氯化。产物 2,4,6-三氯苯胺通过还原其重氮盐转化为 1,3,5-三氯苯。苯胺的氨基甲酸甲酯与 NCS 反应仅产生 2,4-二氯苯基氨基甲酸酯。
