A new simple and efficient transformation of various aromatic ketones to the corresponding halo (dihalo) alkenes is described. The reaction proceeds under mild conditions to give the target products in good yields.

SnCl4–Zn complex provided a novel reductive system in the deoxygenative cross-coupling of aliphatic, aromatic, chalcone epoxide and indanone carbonyl compounds to olefins in high yield (55–86%) at reflux temperature in THF. The advantage of this reagent is inexpensive, short reaction time, and high yield compared to the reagents used in the McMurry cross-coupling reaction.
