Regioselective I/Zn-exchange reactions were performed on polyiodinated arenes or heterocycles within 20 minutes at 0–25 °C using the bimetallic combination pTol2Zn·2LiOR [R = (CH2)2N(Me)(CH2)2NMe2] in toluene. The resulting diaryl- or diheteroarylzincs reacted well with allylic bromides and acyl chlorides to provide functionalized (hetero)aryl iodides in good yields.

用于多碘化芳烃和杂环在甲苯中选择性官能化的区域选择性碘/锌交换

使用双金属组合 pTol2Zn·2LiOR [R = (CH2)2N(Me)(CH2)2NMe2] 在甲苯中，在 20 分钟内在 0–25 °C 下对多碘化芳烃或杂环进行区域选择性 I/Zn 交换反应。所得二芳基-或二杂芳基锌与烯丙基溴和酰氯反应良好，以良好的产率提供官能化的（杂）芳基碘化物。
