A new acyl–acyl exchange reaction has been developed for the formation of aryl esters from primary aryl amides. The reaction could occur under mild reaction conditions with catalytic quantities of K2CO3, and could afford moderate to good yields of the desired products.
已经开发了一种新的酰基-酰基交换反应,用于由伯芳基酰胺形成芳基酯。该反应可以在温和的反应条件下用催化量的K 2 CO 3进行,并且可以提供中等至良好产率的所需产物。
