this research is the synthesis of a novel acidic nanocatalystusing the layer-by-layer assembly technique. The CoFe2O4@TRIS@sulfated boric acid nanoparticles were easily synthesized and studied as a highly beneficial, recyclable, and magnetite nanocatalyst for the synthesis of 2-amino-3-cyanopyridine derivatives. The chemical structure of CoFe2O4@TRIS @sulfated boric acid nanocatalyst was completely confirmed

Three facile and efficient routes for one-pot, cobalt (II) nitratehexahydratecatalyzed multi-component synthesis of 2-amino-3cyanopyridine and pyranopyrazole derivatives have been developed. The present protocols offer the products in good yields from the simple and readily available starting materials. The other salient features of these protocols are operational simplicity, easy isolation of product
