Synthesis of Bis‐Thiazolidinones Using Chitosan‐attached Nano‐CuFe2O4 as an Efficient and Retrievable Heterogeneous Catalyst

The preparation of bis‐thiazolidinones has been achieved by a one‐pot condensation reaction of araldehydes, ethylenediamine, and 2‐mercaptoacetic acid in the presence of nano‐CuFe2O4@chitosan under reflux conditions in toluene. The catalyst was characterized by powder X‐ray diffraction (XRD), scanni...

Description
Summary:The preparation of bis‐thiazolidinones has been achieved by a one‐pot condensation reaction of araldehydes, ethylenediamine, and 2‐mercaptoacetic acid in the presence of nano‐CuFe2O4@chitosan under reflux conditions in toluene. The catalyst was characterized by powder X‐ray diffraction (XRD), scanning electronic microscopy (SEM), vibrating sample magnetometer (VSM) measurements, thermal gravimetric analysis (TGA), and FT‐IR spectroscopy. This method provides several advantages including excellent yields, wide range of products, reusability of the catalyst, and a low amount of the catalyst. A new method is developed for the synthesis of bis‐thiazolidinones by a one‐pot condensation reaction of araldehydes, ethylenediamine, and 2‐mercaptoacetic acid in the presence of nano‐CuFe2O4@chitosan under reflux conditions in toluene. The catalyst was characterized by powder X‐ray diffraction, scanning electronic microscopy, vibrating sample magnetometer, thermal gravimetric analysis, and FT‐IR spectroscopy.
