The reaction of n-butyllithium with 2,3,4,5,6-pentachloro-N,N-dimethyl- benzylamine proceeds by metalhalogen exchange at the positions meta and para to the dimethylaminomethyl group, but not at the ortho position. Coordination by the substituent thus plays little or no part in determining which position undergoes reaction.
正丁基锂与2,3,4,5,6-五氯-N,N-二甲基-苄基胺的反应是通过金属卤素交换在二甲基氨基甲基的间位和对位进行的,而不是在邻位进行的。因此,在确定哪个位置进行反应时,取代基的配位作用很小或没有作用。
