An elimination-addition mechanism, probably involving a "benzyne" intermediate, has been established for the rearrangements which often occur in the conversion of non-activated aryl halides to arylamines with metallic amides. The evidence for the "benzyne" intermediate was obtained through ^(14)C-tracer studies of rearrangements with halobenzenes and experiments designed to determine the role of the
一种消除加成机制,可能涉及“苄”中间体,已经为重排建立了重排,这种重排经常发生在用
金属酰胺将未活化的芳基卤转化为芳胺的过程中。“苄”中间体的证据是通过 ^(14) C-示踪剂研究卤代苯重排和实验设计来确定位于被取代的卤素原子邻位的氢原子的作用获得的。
