Catalytic intermolecular allyl-allyl cross-couplings between alcohols and boronates

We developed catalytic intermolecular C(sp(3))-C(sp(3)) cross-couplings between various allyl alcohols and allyl boronates, which proceeded smoothly in the presence of nickel(0) under mild conditions to form 1,5-dienes with excellent linear- and gamma-selectivity; the use of boronates proved to be crucial in terms of reactivity.
