A palladium/norbornene catalyzed two-component coupling process involving acylation/cyanation of aryl iodides is reported. In this work, aryl acyl nitrile compounds are cleverly selected to provide both nitrile and acyl sources by palladium-catalyzed cleavage of the C–CN bond as both an electrophilic reagent and a termination reagent. This is the first example of C–CN bond cleavage bifunctionalization
报道了钯/降冰片烯催化的双组分偶联过程,涉及芳基碘化物的酰化/氰化。在这项工作中,巧妙地选择了芳基酰基腈化合物,通过钯催化的 C-CN 键断裂来提供腈和酰基源,作为亲电试剂和终止试剂。这是芳基碘化物 C-CN 键断裂双功能化的第一个例子。经过一系列重要的NBE衍生物的筛选,顺利得到了芳基碘化物双官能化产物。该策略具有广泛的底物范围和良好的官能团兼容性。此外,该合成方案在合成各种O 、 N 、 C取代的异吲哚啉酮方面表现出良好的应用。
