The direct oxidative N-acylation reaction of primary amides with aryl/α,β-unsaturated aldehydes was achieved in the presence of azolium salt C3 and an inorganic base using 3,3′,5,5′-tetra-tert-butyldiphenoquinone as the oxidant, thus providing an efficient approach for the synthesis of three types of imide compounds including N-sulfonylcarboxamides, N-sulfinylcarboxamides, and dicarboxyimides in good
直接氧化Ñ伯酰胺与芳基/α,β不饱和醛在氮鎓盐的存在下实现的酰化反应C3和无机碱使用3,3',5,5'-四-叔-butyldiphenoquinone作为氧化剂,因此为以高收率合成三种类型的酰亚胺化合物(包括N-磺酰基羧酰胺,N-亚磺酰基羧酰胺和二羧酰亚胺)提供了一种有效的方法。
