Cp*Rh-III-Catalyzed Arylation of C(sp(3))-H Bonds

摘要

The first Cp* Rh-III-catalyzed arylation of unactivated C(sp(3))-H bonds is presented. The unactivated primary C(sp(3))-H bond of 2-alkylpyridines can be activated by Rh-III and further reacts with triarylboroxines to efficiently build new C(sp(3))-aryl bonds. The methodology also provides a facile and efficient synthesis of unsymmetrical triarylmethanes by Rh-III-catalyzed C(sp(3))-H arylation of diarylmethanes.
