A palladium-catalyzed reductive cross-coupling of 1,3-dienes with boronic esters in which a pi-allyl Pd species is generated directly from a 1,3-diene via a Pd-catalyzed aerobic alcohol oxidation is reported. Both the scope of the process and the origin of a highly selective 1,2-addition are discussed.
