Versatile directed aromatic C–H bond activation and oxidative coupling with allylicalcohols is reported using a cationic Rh(III) catalyst. This method provides efficient and robust synthesis of functional β-aryl ketones and indolines in good yields with excellent regioselectivity, even the reaction runs at 3 g scale. The catalytic systems have good functional group tolerance, such as CONR2, NHAc,
Ruthenium- and rhodium-catalyzed oxidative couplings between versatile directed aromatic C–H bonds and allylicalcohols have been achieved. This method provides efficient synthesis of functional β-aryl ketones and aldehydes in good to excellent yields, and the carbonyl group in the desired products was a significant synthon for organic synthesis.
