摘要：

The chemoselectivity of ruthenium-catalyzed C-H bond arylations on triazol-4-yl-substituted arenes was found to depend on the substitution pattern of both substrates. While various aryl chlorides led to products stemming from direct arylations, ortho-substituted aryl halides in combination with ortho-alkylated arenes preferentially resulted in oxidative homo-couplings.
