green synthesis of tetrahydrodipyrazolopyridine derivatives using nife2o4@tris magnetic nanocatalyst via one-pot multicomponent reaction

In this work, a new magnetic nanocatalyst nife2o4@tris has been introduced to prepare tetrahydrodipyrazolopyridine derivat. this nanocatalyst was synthesized in several steps and was identified using various techniques such as ft-ir, sem, edx, tga, xrd, and vsm. using this magnetic nanocatalyst, tetrahydrodipyrazolopyridine derivatives were synthesized under optimal conditions in water solvent and room temperature with high efficiency and short reaction time. the advantages of this catalyst can be mentioned in its simple preparation, easy separation, and reusability.
