Abstract:Benzothiazole-2-sulfonyl chloride was prepared using 2-mercaptobenzothiazole and 10% sodium hypochlorite as raw materials. When the molar ratio of 2-mercaptobenzothiazole to10% sodium hypochlorite was 1∶6.12; the reaction temperature was -10℃; and the reaction time was 6 h; the yield of Benzothiazole-2-sulfonyl chloride was 85. 8%. Chemical structure of the final product was also confirmed using 1H NMR and ESI-MS. |
Key words:benzothiazole-2-sulfonyl chloride; 2-mercaptobenzothiazole; synthesis |
