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。

The rhodium(III)-catalyzed direct functionalization of aniline C-H bonds with [small alpha]-diazo compounds is described. These transformations provide the facile construction of ortho-alkylated anilines with diazo malonates or highly substituted indoles with...
A copper-mediated multi-component reaction was developed through isocyanide insertion into N–H bonds of less active secondary arylamines. This approach leads to an efficient synthesis of unsymmetrical tetrasubstituted ureas in one pot.

-Aryl-2-aminopyrimidines with Sulfoxonium Ylides to Access 2-Alkyl Indoles Through C-H Bond Activation
A novel synthesis of 2‐alkyl indoles that uses N‐aryl‐2‐aminopyrimidines and sulfoxonium ylides was developed. It is an efficient and mild method for the synthesis of 2‐alkyl indoles. environmentally friendly solvents, efficient alternative carbenoid precursors, and novel catalyst system were used to complete this reaction. Many different directing groups can be used in this process, and the reaction
