Even acyclic tertiaryamines such as triethylamine, tri-n-propylamine and tri-n-butylamine, which have been believed to be inert to aromatic and heteroaromatic halides, underwent SNAr reactions with aromatic and heteroaromatic halides to give the dialkylamino derivatives; in the case of monocyclic amines like N-methylpyrrolidine and N-methylpiperidine, the dealkylation being regioselective.
甚至被认为对芳族和杂芳族卤化物呈惰性的无环叔胺,如三乙胺,三正丙胺和三正丁胺,也与芳族和杂芳族卤化物进行S N Ar反应,得到二烷基氨基衍生物;在单环的胺等的情况下Ñ -甲基吡咯烷和Ñ甲基哌啶,脱烷基化区域选择性被。
