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

We developed a solvent-free, mild, and efficient protocol for Heck–Mizoroki reactions under ultrasonic irradiation in open air, which would be predictable and robust using a range of substrates.

design and development of two palladium-catalyzed redox cascade methods that enable direct β-arylation of ketones. Palladium-catalyzed ketone dehydrogenation, aryl-X bond activation and conjugate addition were merged into a redox-neutral catalytic cycle. Non-metal-based aryl electrophiles were used as both the oxidant and the aryl source. The β-arylation with aryliodides was achieved site-selectively
