A rhodium-catalyzed oxidative acylation of benzamides with aryl aldehydes via direct sp(2) C-H bond cleavage is described. In the presence of Cp*RhCl(2), AgSbF(6), and silver carbonate as an oxidant, N,N-diethyl benzamides can be effectively carbonylated to yield ortho-acyl benzamides.
描述了铑催化的通过直接 sp(2) C-H 键断裂的苯甲酰胺与芳醛的氧化酰化反应。在 Cp*RhCl(2)、AgSbF(6) 和碳酸银作为氧化剂的存在下,N,N-二乙基苯甲酰胺可以有效地进行羰基化反应,生成邻位酰化苯甲酰胺。
