a facile synthesis of 2,3-dihydroquinazolin-4(1h)-ones catalyzed by fumaric acid

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 ...

Efficient synthesis of 2,3-dihydroquinazolin-4(1H)-ones using nano-sized protonated ZSM–5 as a biodegradable and reusable solid acid catalyst

Nano-sized protonated ZSM–5 ( H-ZSM-5nanozeolite) was successfully synthesized by the hydrothermal method using the bagasse ash (BGA) as a new silica source. Cultivated BGA in the south of the Caspian Sea (Mazandaran province, Iran) was used for extracting silica powder. H-ZSM-5 was characterized by Fourier transform infrared (FT-IR), X-ray diffraction (XRD), scanning electronic microscopy (SEM...
