Functionalized aromatic iodides possessing an ester, cyano, chloride or keto group can be converted to arylzinc iodides by reaction with zinc in DMF or DMAC. After transmetallation to the corresponding arylcopper, they react with several electrophiles such as enongs, allylic halides and benzoyl chloride to afford highly functionalized aromatic compounds. Extension to the preparation of polyfunctionalized
具有酯,氰基,氯或酮基的官能化芳族碘化物可通过在DMF或DMAC中与锌反应转化为芳基碘化锌。在金属转移成相应的芳基铜后,它们与几种亲电试剂如烯酮,烯丙基卤化物和苯甲酰氯反应,得到高度官能化的芳族化合物。尽管将锌插入到纯的(E)-烯基碘化物中也提供了烯基碘化锌的E / Z混合物,但扩展到多官能化杂芳族碘化碘化物的制备和烯基锌碘化物的制备也是成功的。
