Abstract
In this study, a novel and highly efficient catalyst was produced from a reaction between silica chloride and sodium hydrogen carbonate. This novel catalyst was named silica sodium carbonate (SSC), and was characterized by FT-IR, XRD, XRF and TG-DT analyses, atomic absorption and titration with HCl (0.01N). Furthermore, herein, the first application of SSC as a green, highly efficient and recyclable catalyst to the synthesis of new 1,4-dihydropyrano[2,3-c]pyrazoles is successfully examined. Compared to the classical reactions for the synthesis of 1,4-dihydropyrano[2,3-c]pyrazoles, the presented procedure using SSC has some advantages than others such as excellent yields of products, short reaction times, green and safety procedure, easy handling and reusability of catalyst.
