Abstract

Aromatic aldehydes and ketones react with ketene under Lewis acid catalysis to produce β- lactones, which in situ react with another molecule of ketene to produce 3-arylglutaric anhydrides. The mechanism, scope, and limitation of this one-pot synthesis of 3-substituted glutaric anhydrides are discussed.
