Allylicarylation of cinnamyloxyphenylboronic acid pinacol esters 3, which have arylboronicacid moiety and allylicether moiety, using a hydrazone 1d–Pd(OAc)2 system proceeded and gave the corresponding 1,3-diarylpropene derivatives 4 with a phenolic hydroxyl group via a selective coupling reaction of the π-allyl intermediate to the boron-substituted position of the leaving group.
