Sulfated tungstate catalyzed an efficient and ecofriendly protocol has been described for the synthesis of 2-substituted benzothiazoles. The corresponding benzothiazoles were obtained using a condensation reaction of 2-aminothiophenol with various aldehydes under ultrasound irradiation at room temperature. Various functional groups on the 2-aminothiophenol as well as on the aldehydes were tolerated to provide 2-substituted benzothiazoles derivatives in excellent yields. The faster reaction rate, solvent-free or mild reaction conditions, wide functional group compatibility, excellent yields, easy work-up procedure, and excellent catalyst recyclability are the advantages of this protocol. These advantages make this process more practicable, cost-effective, and environmentally benign.
Pentafluorophenylammonium Triflate: A Mild, Efficient and Reusable Catalyst for the Synthesis of 2-Arylbenzothiazole and 2-Arylbenzothiazoline Derivatives in a Green Chemical Approach
Datta, Arup
, p. 95 - 102 (2021/03/29)
In this work, one pot, simple and environmentally benign effective synthesis of 2-substituted benzothiazole and benzothiazoline derivatives are described in presence of PFPAT (pentafluorophenylammonium triflate) catalyst in water successfully. A series of benzothiazole derivative were synthesized by the reaction between 2-aminothiophenol and various aldehydes in good yields. Recyclability of the catalyst is observed for four times without loss of its activity in aqueous medium.
