A convenient, effective, mild and simple strategy has been developed for the synthesis of alkenyl halides by the intermolecular addition of benzylic alcohols to aromatic alkynes. The reactions were carried out in the presence of iron(III) bromide or chloride in 1, 2-dibromoethane without additives in air at room temperature. Alkenyl bromides and chlorides were obtained with high regio- and stereoselectivity (E/Z up to 99:1) in good-to-excellent yields in 0.5-1 h under mild reaction conditions.

A novel, simple, and straightforward one-pot reaction of alkynes with various alcohols in the presence of iron salts (FeCl3 and FeBr 3) was described to yield the corresponding alkenyl halides with complete regioselectivity and high
Formation of Disubstituted Chloro-olefins by Treatment of Substituted 1,2-Dichloroethylenes with Hydrocarbons in the Vapour Phase

Disubstituted chloro-olefins RCH=CR1Cl together with hydrogen chloride have been formed by treatment of substituted 1,2-dichloroethylenes with hydrocarbons in the gas phase in a flow system at 500 to 600 deg C.Some stereoselectivity towards formation of the Z isomers was observed.The results are interpreted in terms of a free-radical chain mechanism.
