| Abstract: | The novel 1,12-dithia macrocycles based on dibenzo substituents,5 (S2O3), 6 (S3O2) and 7 (S2O4) have been synthesized by cesium carbonatepromoted ring closure reactions of 2,2'-(ethylenedioxy)bis(benzyl chloride), 3, with the appropriate dithiols under high dilution condition in reasonable yields. The structures of macrocycles 6 and 7 have been characterized by X-ray crystallography. |
