very effective for the preparation of 2-amino-3-cyanopyridine and pyranopyrazole derivatives in solvent-free conditions. This nanocatalyst was easily separated from the reaction medium using an external magnet and used at least five times in a row under optimal reaction conditions with a slight reduction in the activity of the recycled catalyst. Producing products with good to excellent yields, the need
