A convenient and regioselective cross-coupling of heteroaryl boronic acids with allylic alcohols under catalyst-free reaction conditions is described. The developed procedure is simple, works under external oxidant- and metal-free conditions, and proves to be very general with an unprecedented ortho-selectivity. This approach represents one of the very few examples of ortho-functionalization of boronic acids.
