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...

متن کاملLight promoted synthesis of 1,8-dioxooctahydroxanthenes using sulphated tin oxide as solid support catalyst
In the past few years multi component reactions have captured the attention of synthetic chemists as they provide easy access to diverse complex organic molecules through carbon - carbon and carbon - heteroatom bond formations in tandem manner with simple easy to carry out reaction conditions in short time. 1,8-dioxo-octahydroxanthene is a significant class of oxygen containing...
متن کاملAn efficient and one-pot green synthesis of 2-arylsubstituted benzimidazoles catalyzed by nano-Fe3O4@silica sulfuric acid as a recyclable nanomagnetic solid acid catalyst
An efficient and green protocol for the synthesis of 2-arylsubstituted benzimidazoles via a condensation reaction of aromatic aldehydes and 1,2-phenylenediamine using nano-Fe3O4@SiO2-SO3H as a solid acid catalyst in ethanol under reflux conditions has been described. The reactions are completed in short times, and the corresponding benzimidaz...
