The direct amidation of carboxylicacids with N-substituted formamides has been accomplished via ruthenium catalysis. In the presence of ruthenium catalyst, a versatile range of carboxylicacids and N-substituted formamides undergoes amidation reaction to produce synthetically useful amides in good yields. CO in amide product came from benzoic acid but not N-substituted formamides, and which was confirmed
Abstract Herein we report a robust and synthetically useful catalyst-free amination methodology by the coupling of carboxylic acids and N-substituted formamides using POCl3 as a promoter. Versatile amides with a wide array of substituent groups were prepared within only 1 h in good to excellent yields. And even multi-substituted aromatic carboxylic acids could give the desired products with satisfactory
摘要在此我们报告了一种稳健且合成有用的无催化剂胺化方法,该方法通过使用 POCl3 作为促进剂将羧酸和 N 取代甲酰胺偶联。具有多种取代基的多功能酰胺仅在 1 小时内就以良好到极好的收率制备。甚至多取代的芳族羧酸也可以得到令人满意的结果。图形概要
