Abstract:2-Chlorobenzothiazole was prepared using 2-mercaptobenzothiazole as the starting material at a temperature of -5℃ in the presence of hydrochloric acid and sodium hypochlorite. A typical yield of 91.7% was obtained; the product was confirmed by ESI-MS and 1H NMR spectra. This method has many advantages including simple manipulation, commercialized raw materials, environmental friendliness and high yield. |
Key words:2-chlorobenzothiazole; 2-mercaptobenmthiazol; sodium hypochlorite |
