Herein we report a direct β-arylation of simple ketones with widely available aryliodides, combining palladium-catalyzed ketone oxidation, aryl-halide activation, and conjugate addition through a single catalytic cycle. Simple cyclic ketones with different ring-sizes, as well as acyclic ketones, can be directly arylated at the β-position with complete site-selectivity and excellent functional group

Disclosed is a method for the β-C—H H functionalization of carbonyl compounds that is both selective and broadly applicable. The methods provide direct β-arylation of carbonyl compound with a diverse array of aryl or heteroaryl halides, aryl or heteroryl tosylate, aryl or heteroaryl triflates, or diaryliodonium salts, by palladium catalysis in the presence of a ligand and promoter.
