A cleaner and greener method of synthesis of 3H-benzothiazole-2-thione is being reported in this communication. In this method, various o-iodoaniline derivatives are reacted with carbon disulfide in the presence of Cs2CO3 and tetramethyl ammonium bromide (TMAB) to give 3H-benzothiazole-2-thione and its derivatives in higher yields.
