Synthesis, characterization and investigation of catalytic activity of new catalyst based on HMS for multicomponent reaction

This research has developed for synthesis of mesoporous catalyst based on Hexagonal Mesoporous Silica (HMS/Pr-PTSC-Cu). The morphology and chemistry of the synthesized heterogenous catalyst was characterized by FT-IR, SEM and EDX. Then, the catalytic performance of HMS/Pr-PTSC-Cu was investigated for synthesis ۱,۴-dihydropyrano[۲,۳- c]pyrazole derivatives. The prepared catalyst can be able reused several times without any noticeable loss in catalytic activity.
