Efficient one-pot synthesis of pyrazoles catalyzed by nano-crystalline solid acid catalyst
An efficient and green protocol for the synthesis of pyrazoles derivatives by one-pot reaction of different 1,3-dicarbonyl compounds with hydrazines/hydrazides has been developed using nano-sulfated zirconia, nano-structured ZnO, nano-g-alumina and nano-ZSM-5 zeolites, as the catalyst. The optical properties of the nano-structured catalysts and organic molecules were studied. The advantages of ...

15 صفحه اولPreparation and application of HMCM-22 zeolite as an efficient solid acid catalyst for the synthesis of acetals
HMCM-22 with a Si:Al molar ratio of 15:1 has been shown to effectively catalyze the synthesis of acetals with 100% selectivity by the reaction of aldehydes with methanol under reflux conditions. Platelet HMCM-22 particles were prepared by the static strategy and characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FT-IR), BET tech...
