Well‐defined ruthenium(II) phosphinousacid (PA) complexes enabled chemo‐, site‐, and diastereoselective C−H functionalization of arenes and alkenes with ample scope. The outstanding catalytic activity was reflected by catalyst loadings as low as 0.75 mol %, and the most step‐economical access reported to date to angiotensin II receptor antagonist blockbuster drugs. Mechanistic studies indicated a

Mechanistic studies revealed ruthenium-catalyzed direct arylations to proceed through reversible C-H bond activation and subsequent rate-limiting oxidative addition with aryl halides, which led to the development of widely applicable well-defined ruthenium(II) carboxylate catalysts.
