A simple manganese catalyst sets new standards in the ortho-C−H allylation of benzoates, by allowing nearly complete selectivity for mono- over competing di-allylation. The reaction can be combined with an in situ decarboxylation, giving access to allylarenes in substitution patterns that are otherwise hard to obtain. The scope of the protocol is demonstrated by 44 diverse examples.
一种简单的锰催化剂为苯甲酸酯的邻位-C−H 烯丙基化设定了新的标准,它允许对单一竞争性双烯丙基化几乎完全选择性。该反应可以与原位脱羧相结合,从而以其他方式难以获得的取代模式获得烯丙基芳烃。该协议的范围由 44 个不同的例子展示。
