All in one : A tandem strategy has been developed wherein secondary aryl alcohols are directly coupled with aryl halides to provide stilbenoids through a dehydrative Heck sequence in the ionic liquid [hmim]Br, and with water as a by‐product under microwave irradiation (see scheme). Classical methods do not permit this sequence to proceed in one pot, and some methods require multiple steps. hmim=1‐ n ‐hexyl‐3‐methylimidazolium.
