Mild Rh(III)-Catalyzed Direct C–H Bond Arylation of (Hetero)Arenes with Arylsilanes in Aqueous Media
摘要:
An efficient rhodium(III)-catalyzed C-H bond activation and further direct arylation of (hetero)arenes with organosilanes in aqueous media was developed. This reaction shows good substrate scope and excellent functional group compatibility and gives the products in good yields with excellent regioselectivity.

A RhI‐catalyzed direct C2‐arylation of indoles with diversely substituted arylcarboxylicacids has been developed using 2‐pyrimidyl group as an easily installable and readily removable N‐directing group. The reaction proceeded smoothly without the need for any external oxidants under relatively mild conditions to produce the C2‐arylated indoles in high yields with excellent regioselectivity. A range
