Green Synthesis and Antioxidant Activity Investigation of New Thiazinotriazines: Reduction of Organic Pollutant Using Fe3O4/TiO2/CuO@MWCNTs MNCs

The Petasites hybridus rhizome water extract was used as a green media for the preparation of the Fe3O4/TiO2/CuO@MWCNTs magnetic nanocomposites (Fe3O4/TiO2/CuO@Multi-Walled Carbon Nanotubes) and its activity was evaluated by using it in the one-pot multicomponent reaction of isatoic anhydrides, electron deficient acetylenic compounds, alpha-haloketones, ammonium acetate, isothiocyanates and hydrazoyl chloride in aqueous media at room temperature for the production of novel derivatives of thiazinotriazines in excellent yields. Moreover, reduction of organic pollutants such 4-nitrophenol (4-NP) was performed by synthesized Fe3O4/TiO2/CuO@MWCNTs magnetic nanocomposites in water at room temperature. The outcomes showed this catalyst decreased organic pollutants in few seconds. The synthesized thiazinotriazines have OH and NH functional groups that have acidic hydrogen and show high antioxidant activity. The employed process for the production of thiazinotriazines has some benefits such as short time of reactions, excellent efficiency of product, easy separation of catalyst and products.
