During the past decades, advances in nanoscience and nanotechnology have pushed forward the synthesis of functional magnetic nanoparticles (MNPs), which is one of the most active research areas in advanced materials. MNPs that have unique magnetic properties and other functionalities have enabled a wide spectrum of applications. Iron oxide magnetic nanoparticles (Fe3O4-MNPs) are approximately 20–30 nm in size containing a single magnetic domain with a single magnetic moment and exhibit superparamagnetism. Magnetic nanocatalysts can easily be separated and recycled from the products by an external magnet [1].Tetrazoles are an important class of five-membered ring heterocycles broadly used in pharmaceuticals, agrochemicals, and material science [2]. In this study, we report Ni (П) Isatin/ Dopamine@Fe3O4as a new heterogeneous catalyst for the synthesis of 5-substituted 1H-tetrazoles in PEG(Figure 1). This method is an efficient and rapid route for the synthesis of a wide range of substituted 1H-tetrazoles.
