- Abstract
In this study, a new and procedure was reported for the synthesis of Ag/TiO2/Fe3O4@MWCNTs MNCs as a new heterogeneous organometallic catalyst. XRD, FESEM, EDX, and TEM analysis were used for confirming the structure of synthesized nanocatalyst. The Ag/TiO2/Fe3O4@MWCNTs MNCs as a high performance catalyst was employed for the preparation of a new family of functionalized spiropyridine via the one‐pot condensation reactions of acetophenones, diethyloxalate, ammonium acetate, isatin, malononitrile, and electron‐deficient acetylenic compounds in water at room temperature. Also, antioxidant property of some prepared compounds was investigated using diphenyl‐picrylhydrazine (DPPH) radical trapping experiment. Presently, bacteria that are not destroyed with drug have generated many problems in the performance of many transferable disease. For this reason, discovering appropriate and new procedures for the dealing with these pathogens is important, and recent study has focused on the investigation of the antibacterial effects on the prepared compounds.
