allylic alcohols to 1,5-dienes in the presence of B2pin2 with excellent regioselectivity has been developed. Mechanistic studies indicate that the reaction proceeds via sequential nickel-catalyzed borylation of allylalcohols followed by cross-coupling of the resulting allyl boronates with allylalcohols. The method was effectively applied to nickel-catalyzed allylation of aldehydes using allylic alcohols
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.

A highly efficient metal-free intermolecular C(sp3)âC(sp3) allylâallyl cross-coupling protocol between allyl acetates and allyltrimethylsilanes, which proceeded smoothly in the presence of catalytic triflimide to form 1,5-dienes with good to excellent regioselectivity, has been developed.
