Microwave-assisted thioacetalization of carbonyl compounds using Al-MCM-41 as an efficient heterogeneous catalyst
In this project various types of carbonyl compounds were efficiently converted to their corresponding 1,3-oxathiolanes with 2-mercaptoethanol in the presence of catalytic amount of Al-MCM-41 with microwave energy. The catalyst can be reused several times without loss of its catalytic activity. Very short reaction times, reusability of the catalyst, and easy workup are noteworthy advantages of ...

-OSO3H Functionalized Mesoporous MCM-41 Coated on Fe3O4 Nanoparticles: an Efficient and Recyclable Nano-Catalyst for Preparation of 3,2′-Bisindoles
Mesoporous MCM-41 was coated on Fe3O4 nanoparticles and then functionalized with sulfurochloridic acid to provide a core-shell solid acid nano-catalyst. The catalyst was characterized by transmission electron microscopy (TEM), infrared spectroscopy (FTIR), X-ray diffraction (XRD), thermogravimetric analysis (TG), Brunauer-Emmet-Teller analysis (BET) and vibrating sample magnetometery (VSM). The...
متن کاملCu-Mo2C/MCM-41: An Efficient Catalyst for the Selective Synthesis of Methanol from CO2
Supported molybdenum carbide (yMo2C/M41) and Cu-promoted molybdenum carbide, using a mechanical mixing and co-impregnation method (xCuyMo2C/M41-M and xCuyMo2C/M41-I) on a mesoporous molecular sieve MCM-41, were prepared by temperature-programmed carburization method in a CO/H2 atmosphere at 1073 K, and their catalytic performances were tested for CO2 hydrogenation to form methanol. Both catalys...
متن کاملAn efficient green synthesis of highly substituted imidazoles catalyzed by Al-MCM-41 nanoreactors
Al-MCM-41 nanoreactors is found to be a remarkable efficient catalyst for one-pot multicomponent cyclocondensation of benzil, aniline or ammonium acetate and aromatic aldehydes for the synthesis of polysubstituted imidazoles under solvent-free conditions. The reaction was efficiently promoted by 10 mg nano-Al-MCM-41 and the heterogeneous catalyst was recycled for four runs in this reaction with...
