Gallium chloride catalyzed acylation of alkynes was studied to afford one of the most atom-economic and efficient methodologies for the preparation of β-chlorovinyl ketones. In contrast to the Friedel-Crafts acylation, only a catalytic amount of GaCl3 was needed to produce the target products in high stereoselectivity.
