New base hybrid catalysts, based on silyl-derivatives of mols. carrying amino, diamino, pyrrolidine, pyrazolium and imidazolium functionalities were successfully achieved through post synthetic grafting onto M41S-type support. Different characterization techniques were implemented to study the characteristics of the materials, such as elemental anal., solid state MAS NMR and FTIR spectroscopies, X-ray diffraction (XRD), thermogravimetric and differential thermal analyses (TGA-DTA) and textural properties through N2 physisorption anal. The catalytic activity and recyclability of these compounds as base catalysts was demonstrated for C-C bond forming reactions such as Knoevenagel condensations and Michael additions rationalizing the differences observed as function of the reaction mechanisms. An enamine mechanism was proposed for Knoevenagel condensations and an enolate mechanism for Michael additions The experimental process involved the reaction of 1-Methylpyrazole(cas: 930-36-9Recommanded Product: 930-36-9)
1-Methylpyrazole(cas: 930-36-9) belongs to pyrazoles. Pyrazole derivatives have been reported to exhibit a wide range of applications in medicinal chemistry and pharmacology. A large number of drugs incorporating pyrazole structure have been utilized as partial agonists for nicotinic acid receptors, antidepressants, antimicrobial agents, antiviral agents, and antifungal agents solely or along with the combination of other structural motifs.Recommanded Product: 930-36-9
