SYNTHESIS AND ELECTROCHEMICAL PROPERTIES OF 2,2 '-BIGUAIAZULENE-BASED 1,2-DITHIIN AND THIOPHENE

摘要

The synthesis of diguaiazuleno[3,2-c:2',3'-e][1,2]dithiin was achieved by the reaction of 2,2'-biguaiazulene with disulfur dichloride/imidazole as a sulfuration reagent. Thermolysis of the dithiin afforded the corresponding desulfurized compound, diguaiazuleno[3,2-b:2',3'-d]thiophene. Cyclic voltammetry of the S-heterocycles showed one reversible wave at the reduction region, respectively.
