摘要
以２，２’二甲基４，４’联苯二胺盐为原料，经重氮化碘代，氰基取代等４ 步反应，合成了２，２’二甲基联苯４ ，４’二甲酰氯。重氮化碘代反应产率为７４ ％ ，氰基取代反应产率为８６％ 。
Dimethylbenzidine dihydrochloride is used as raw material,2,2' dimethylbiphenyl 4,4' dicarbonyl dichloride is synthesized by four step reactions.The yield of diazotization iodosubstitution is 74%,the yield of cyano substitution reaches 86%.The structures of the products are identified by IR and \+1 H NMR spectroscopy.
