Indium chloride catalyzed alkylative rearrangement of propargylic acetates into α-alkyl-α,β-unsaturated carbonyl compounds has been achieved. Propargylic acetates functioned as α-acylvinyl anion equivalents to react with carbocations generated from alkyl chlorides. Other alkyl electrophiles such as alcohols and acetates were also applicable.
