Magnetic nanoparticles have gained a great deal of attention from both academic and industrial point of view, owing to their unique properties including high surface area, and superparamagnetism, which enable them to be suitable for modification with many compounds and employing them as a catalyst in organic reactions. In this mini-review, we have summarized the application of surface-modified magnetite nanoparticles as magnetically recoverable catalysts in heterocyclic synthesis. These catalysts include silica, biopolymer, acid, amine, transition metal, ionic liquid and metal organic framework supported magnetite catalysts.
