Efficient Ru-catalyzed regioselective C–H oxygenation of N-aryl-2-pyrimidines is described with aryl carboxylic acids in the presence of AgSbF6 as an additive and Ag2CO3 as an oxidant. The reaction can be extended to alkyl, heteroaryl, and α,β-unsaturated carboxylic acids. The regioselectivity, broad substrate scope, and functional group tolerance are the significant practical advantages.
描述了在AgSbF 6作为添加剂和Ag 2 CO 3作为氧化剂的情况下,使用芳基羧酸对N-芳基-2-嘧啶进行Ru催化的区域选择性C–H氧化。该反应可以扩展至烷基,杂芳基和α,β-不饱和羧酸。区域选择性,广泛的底物范围和官能团耐受性是显着的实际优势。
