Synthesis of a variety of 2-substituted benzothiazoles using ZnO nanoparticles as catalyst under solvent-free reaction conditions has been successful, with good to excellent yields and broad functional group compatibility. The protocol offers advantages such as faster reaction rate, mild conditions, easy recovery of materials, and excellent catalyst recyclability, making it a more feasible, economical, and environmentally benign process.
The synthesis of 2-substituted benzothiazoles has been described using ZnO-nanoparticles as a catalyst. The condensation of 2-aminothiophenol and aryl/alkyl nitriles resulted in the formation of various 2-substituted benzothiazoles under solvent-free reaction conditions. The library of 2-substituted benzothiazoles has been synthesized in good to excellent yield. The reaction has shown a wide range of functional group compatibility for both varyingly substituted 2-aminothiophenols and nitriles. The protocol has many advantages such as faster reaction rate, mild reaction conditions, various functional group compatibility, excellent yield, solvent-free reaction conditions, easy recovery of materials, and excellent catalyst recyclability, among others. The various advantages of this protocol make it a more feasible, economical, and environmentally benign process.
