Vinyl chlorides and bromides are obtained in good yield from the corresponding ketones and acetylhalides in the presence of trifluoroacetic or trifluoromethanesulfonic acid. The Z isomer is selectively formed.

Hydroalumination of olefins with lithium aluminum hydride followed by treatment with various allylic halides in presence of a catalytic amount of copper(I) chloride resulted in coupling. This new development provides a simple operational method for lengthening the carbon chain of olefins.
