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.

The study and application of transitionmetal hydrides (TMHs) has been an active area of chemical research since the early 1960s1, for energy storage, through the reduction of protons to generate hydrogen2,3, and for organic synthesis, for the functionalization of unsaturated C–C, C–O and C–N bonds4,5. In the former instance, electrochemical means for driving such reactivity has been common place since
