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 was1∶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 using1 H NMR and ESI-MS.
