Abstract

1, 3, 5-Tris (2-hydroxyethyl) isocyanurate functionalized SBA-15 is used as a novel, highly efficient. and recyclable heterogeneous nano-catalyst for the one-pot 3-component synthesis of tetrahydro benzo b pyran derivatives. These unique derivatives were synthesized through the condensation reactions of the enolizable compounds, different aldehydes, and malononitrile (or ethylcyanoacetate) under the mild reaction conditions. in the short reaction times. and gives excellent yields in the refluxing H2O as a green solvent. The accuracy of synthesizing functionalized SBA-15 was confirmed with FT-IR spectroscopy. Than the catalyst was characterized by scanning electron microscopy (SEM). transition electron microscopy (TEM). and surface area analysis (BET). TEM images demonstrated that the synthesized catalyst had a hexagonal structure. Simplicity in the operation. rapidity. high yields. low cost. mild reaction conditions. catalyst with low loading, evading the usage of toxic change metals, stability, and the catalyst reusability are the main advantages of the proposed protocol.
