One-pot multicomponent reactions of isatins: Green synthesis of cyclopentatriazine derivatives by employing Ag/Fe3O4/SiO2@MWCNTs MNCs as an efficient catalyst

Using a multicomponent reaction of isatin or benzaldehydes, malononitrile, ethyl 2,4-dioxo-4-arylbutanoate, ammonium acetate, and hydrazonoyl chlorides in aqueous media at room temperature in the presence of Ag/Fe3O4/SiO2@MWCNTs MNCs, this research produced cyclopentatriazines as new derivatives with a high yield. Another investigation in this work examines the antioxidant properties of the produced cyclopentatriazine. The applied method for producing cyclopentatriazine demonstrated a number of desirable traits, including quick reactions, high yields of the final product, and straightforward separation of the product and catalyst from the reaction mixture.
