متن کاملRapid and Green Synthesis of some Benzothiazole-, Benzimidazole- and Benzoxazole-2-thiol Derivatives Using Copper Sulfate in Aqueous Media
In this study an easy, green, efficient and simple approach is reported for the synthesis of some benzothiazole-, benzimidazole- and benzoxazole-2-thiolderivatives. The proposed approach employs the reaction of corresponding aromatic amine with potassium isopropyl xanthate (Z11) in the presence of copper sulfate (CuSO4) as a catalyst under conventional heating and ultrasonic irr...
