unactivated alkyl iodides employing a fac‐Ir(ppy)3‐catalyzed radical aminocarbonylation protocol has been developed. Using a two‐chambered system, alkyl iodides, fac‐Ir(ppy)3, amines, reductants, and CO gas (released ex situ from Mo(CO)6), were combined and subjected to an initial radical reductive dehalogenation generating alkyl radicals, and a subsequent aminocarbonylation with amines affording a
已经开发出一种新颖,温和且简便的方法,可以通过未活化的烷基碘使用fac- Ir(ppy)3催化的自由基氨基羰基化方法制备烷基酰胺。使用两腔系统,将烷基碘,fac- Ir(ppy)3,胺,还原剂和CO气体(从Mo(CO)6异位释放)合并,并进行初始自由基还原性脱卤,生成烷基自由基,然后用胺进行氨基羰基化,以中等到极好的收率提供了广泛的烷基酰胺。
