An efficient, green and scale-up synthesis of amides from esters and amines catalyzed by Ru-MACHO catalyst under mild conditions

摘要

An efficient, green and scale-up synthesis of amides from esters and amines has been developed using Ru-MACHO as a readily available catalyst. A diverse range of amides were obtained in moderate to excellent yields (55-98%). Furthermore, when the scale of the amidation reaction was increased to 240.0 mmol, the desired amide still could be obtained in high yield (48.2 g of N-benzylbenzamide, 95%).
