Palladium(II)-Catalyzed γ-Selective Hydroarylation of Alkenyl Carbonyl Compounds with Arylboronic Acids

A catalytic γ-selective <i>syn</i>-hydroarylation of alkenyl carbonyl compounds using arylboronic acids has been developed using a substrate directivity approach with a palladium(II) catalyst. This method tolerates a wide range of functionalized (hetero)arylboronic acids and a variety of substitution patterns on the alkene.
