Functionalized arylmagnesium compounds prepared via a halogen-magnesium exchange reaction using aryl iodides or bromides and i-PrMgCl·LiCl, react rapidly with benzyl-N-chloroamines at -45 °C providing polyfunctional tertiary amines in good yields. The methodology is also successfully applied to the preparation ofchiral N-chloroamines with retention ofchirality.
通过使用芳基碘化物或溴化物和 i-PrMgCl·LiCl 的卤素-镁交换反应制备的官能化芳基镁化合物在 -45 °C 下与苄基-N-氯胺快速反应,以良好的收率提供多官能叔胺。该方法还成功地应用于制备手性保留的手性N-氯胺。
