A Cu‐(II) catalyzed N‐formylation and N‐acylation of amines with moderate to excellent yields, using N, N‐dimethyl formamide (DMF) and N, N‐dimethyl acetamide (DMA) as a formyl and acylating sources in the presence of 1,2,4‐triazole is reported. This novel, highly efficient and simple protocol shows broad substrate scope for aliphatic, aromatic, and heterocyclic amines. In addition, the conditions
甲CU-(II)催化的Ñ -formylation和Ñ胺的酰化以中等至良好的产率,使用N,N-二甲基甲酰胺(DMF)和N,N-二甲基乙酰胺(DMA),为甲酰基和酰化在源据报道存在1,2,4-三唑。这种新颖,高效且简单的方案显示了脂族,芳族和杂环胺的广泛底物范围。此外,当使用DMF和DMA作为溶剂,并使用各种催化剂,配体和碱时,通常描述了防止胺和芳基卤化物的C-N交叉偶联中的N-甲酰化和N-酰化杂质的条件。
