A Rh(I)-catalyzed ketone Suzuki-Miyaura coupling reaction of benzylacetone with arylboronic acid is developed. Selective C(O)-C bond activation, which employs aminopyridine as a temporary directing group and ethyl vinyl ketone as a hydride acceptor, occurs on the alkyl chain containing a β-position hydrogen. A series of acetophenone products were obtained in yields up to 75%.

A terminal-selective migratory hydroarylation of unactivated olefins has been developed though a NiH-catalyzed alkene isomerization-hydroarylation relay process. This sp3C-H arylation was achieved with a simple pyrox ligand under mild conditions. The practicality and synthetic flexibility of the method is highlighted by the successful regioconvergent conversion of isomeric mixtures of alkenes to value-added linear arylation products on a gram scale.
