Assisted ruthenium-catalyzed C-H bond activation: Carboxylic acids as cocatalysts for generally applicable direct arylations in apolar solvents

摘要

Catalytic amounts of aromatic carboxylic acid MesCO(2)H enabled efficient ruthenium-catalyzed direct arylations in apolar solvents with unparalleled broad scope via a concerted deprotonation-metalation mechanism.
