Insertion of 1-alkene, 2-alkene, and styrene into the ortho C-H bond of benzamide in the presence of an inexpensive cobalt catalyst, DMPU as a crucial ligand, and cyclohexylmagnesium chloride proceeds smoothly at 25 °C to selectively give the ortho-alkylated product. Notable features of this reaction include the structural variety of the alkene and the amide substrate and the tolerance of functional
在廉价的钴催化剂存在下,将 1-烯烃、2-烯烃和苯乙烯插入苯甲酰胺的邻 CH 键,DMPU 作为关键配体,环己基氯化镁在 25°C 下顺利进行,选择性地得到邻烷基化的产品。该反应的显着特征包括烯烃和酰胺底物的结构多样性以及对卤化物、烯烃、酯和酰胺基团等官能团的耐受性。
