(E)-Alkenylzinc iodides were prepared by Fe-catalyzed reductive coupling of terminal arylalkynes with alkyl iodides. In the presence of a copper catalyst, these reagents reacted with allylic bromides derived from Morita-Baylis-Hillman alcohols to give 1,4-dienes in high yields. The reactions are highly gamma-selective (generally gamma/alpha > 49:1) and tolerate a wide range of functional groups such as ester, cyano, keto, and nitro.text::journal::journal article::research article
