Abstract:4,4′-Biphenyldithiol was synthesized using 4,4′-biphenyldisulfonic acid potassium as starting material. In typical process, 4,4′-biphenyldisulfonic acid potassium reacted with PCl5, and then the obtained intermediate reacted with Sn/HCl to give the target product. A total yield of 55.25% with a purity of 99.4% was obtained. This method is economical and environmental friendly satisfying the requirements for industrial production process. |
Key words:4,4′-biphenyldithiol; 4,4′-biphenyldisulfonyl chloride; recrystallization |
