BACKGROUND
In this paper, a novel catalyst is synthesized and characterized by immobilizing copper onto imidazopyridine-modified superparamagnetic iron oxide nanoparticles (SPION).
METHODS
The catalyst is characterized by several methods, including TEM, SEM, ICP, DLS, and VSM. The catalytic activity of the catalyst is evaluated in the synthesis of thiosolfunamide. The synthesized catalyst showed very good activity in the mentioned reaction and performance for synthesizing the desired products in high isolated yields.
RESULTS
For the synthesis of the products, sequential transformations enable the facile synthesis of complex target molecules from simple building blocks in a single preparative step.
CONCLUSION
The reaction can be performed with a high yield using water and ethanol as the reaction green solvent using terminal alkynes and sulfonyl azides as starting materials. The reusability of the catalyst was tested, and the results proved high reusability of the catalyst.
