This note describes the efficient and highly regioselectivesynthesis of 2-(2′-alkenylphenyl)phenol derivatives via palladium-catalyzed 2′-alkenylation of 2-arylphenols directed by the phenolic hydroxyl group using benzoquinone as the oxidant in an atmosphere of air. This reaction can tolerate a series of functional groups and provides the alkenylation products regio- and stereoselectively in moderate
