Various anilides have been directly ortho-acetoxylated through a Pd(OAc)2-catalyzed C−Hbond activation process. The amide group in anilides was found to functionalize as an elegant directing group to convert aromatic sp2 C−H bonds into C−O bonds in high regioselectivity with acetic acid as the acetate source and K2S2O8 as the oxidant.
通过Pd(OAc)2催化的CH键活化过程,各种苯甲酸酯已直接被邻乙酰氧基化。发现在苯甲酸酯中的酰胺基团作为优雅的引导基团起作用,以乙酸为乙酸盐源和K 2 S 2 O 8为氧化剂以高区域选择性将芳族sp 2 C-H键转变为C-O键。
