Metal migration through a carbon chain is a versatile method for achieving remote functionalization. However, almost all known examples involve the overall net migration of alkylmetal species. Here, we report that allylrhodium species obtained from hydrorhodation of 1,3‐dienes undergo chain walking toward esters, amides, or (hetero)arenes over distances of up to eight methylene units. The final, more
通过碳链的金属迁移是实现远程功能化的通用方法。然而,几乎所有已知的例子都涉及烷基金属物质的整体净迁移。在这里,我们报道从1,3-二烯加氢精制得到的烯丙基铑物种在最多8个亚甲基单元的距离上经历向酯,酰胺或(杂)芳烃的链行走。最终的,高度共轭的烯丙基铑物质与醛和亚胺进行亲核烯丙基化反应,分别得到Z-均烯丙基醇和胺。
