A practical α‐alkylation of ketones and aldehydes has been achieved by the direct addition of alcohols to enol acetates. The moderate Lewis acidity of InI3, GaBr3, and FeBr3 is a key factor in the catalytic cycle, and many different alcohols and enol acetates have been successfully used in this procedure.
