Carboacylation of an unsaturated bond represents a powerful transformation. However, only a few examples of carboacylation of alkyne have been reported through C–C bond scission and reconnection. Here, we report a method of carboacylation of an unactivated alkyne by utilizing nonstrained C–C bonds under gold(I) catalysis. The density functional theory computational and experimental studies reveal that
不饱和键的碳酰化代表了强大的转变。然而,仅报道了少数通过C-C键断裂和重新连接进行炔烃碳酰化的例子。在这里,我们报道了一种在金(I)催化下利用非张力 C-C 键对未活化的炔烃进行碳酰化的方法。密度泛函理论计算和实验研究表明,该反应通过溶剂笼嵌套酰基阳离子从 C 到 C 的形式 1,3-酰基迁移进行。
