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-chlorophthalide (8), phtalide (9), or (E)-3[α-(benzoyloxy) benzylidene] phthalide (12); the structure of the latter compound was confirmed by X-ray crystallography.
在各种条件下进行阴极还原,可以有效合成(E)-[1,1'] biisobenzofuranyliden-3,3'-dion(4),[2]-苯并吡喃基[4,3-c]- [2]苯并吡喃-6、12-二酮(7),3-氯邻苯二甲酸酯(8),邻苯二甲酸酯(9)或(E)-3 [α-(苯甲酰氧基)亚苄基]邻苯二甲酸酯(12);后一种化合物的结构通过X射线晶体学证实。
