Abstract

Treatment of acetophenone and dibenzoylmethane with excess oxalyl chloride gave heterocyclization products, 2-(3-oxo-5-phenyl-2,3-dihydrofuran-2-ylidene)-5-phenyl-2,3-dihydrofuran-3-one and a mixture of 4-benzoyl-5-phenyl-2,3-dihydrofuran-2,3-dione with 4-benzoyl-2-dibenzoylmethylene-5-phenyl-2,3-dihydrofuran-3-one.
