Article abstract of DOI:10.1016/S0040-4039(00)84911-4

The cathodic reduction, under various conditions, of phthalyl chloride enables efficient synthesis of (E)-<1,1'>biisobenzofuranyliden-3,3'-dion(4), (2)-benzopyrano <4,3-c>-<2> benzopyrano-6,12-dione (7), 3-chlorophtalide (8), phtalide (9), or (E)-3<α-(benzoyloxy) benzylidene> phtalide (12); the structure of the latter compound was confirmed by X-ray crystallography.
