چکیده
the HY zeolite functionalized based triazine-SO3H has been prepared, characterized by FT-IR, XRD, BET, FE-SEM, TGA, EDX and MAP and used for the green synthesis of the pharmaceutically valuable 1, 4-dihydropyrano[2, 3-c]pyrazole derivatives as a new and efficient heterogeneous catalyst. The reactions were carried out in mild and green conditions and short reaction times with high yield and easy workup process. The heterogeneous nanocatalyst can be simply recovered and reused for at least five times without considerable loss of activity.
