simple, and straightforward one-pot reaction of alkynes with various alcohols in the presence of iron salts (FeCl3 and FeBr3) was described to yield the corresponding alkenyl halides with complete regioselectivity and highstereoselectivity. The reaction is high yielding and works under mild conditions. The iron salts act as Lewis acids and a source of halides. The reaction tolerates a wide variety of functional
