Safaei-Ghomi, Javad; Abbas, Ali Kareem; Shahpiri, Marzieh published the article 《Synthesis of imidazoles promoted by H3PW12O40-amino-functionalized CdFe12O19@SiO2 nanocomposite》. Keywords: amino functionalize phosphotungstic acid catalyst preparation surface area; benzil ammonium acetate aryl aldehyde amino phosphotungsten catalyst condensation; imidazole preparation green chem.They researched the compound: 2,4,5-Triphenylimidazole( cas:484-47-9 ).COA of Formula: C21H16N2. Aromatic heterocyclic compounds can be divided into two categories: single heterocyclic and fused heterocyclic. In addition, there is a lot of other information about this compound (cas:484-47-9) here.
H3PW12O40-amino-functionalized CdFe12O19@SiO2 nanocomposite was applied as an effective nanocatalyst for the preparation of imidazoles by three-component reactions of benzil, ammonium acetate and benzaldehydes under solvent-free condition. H3PW12O40-amino-functionalized CdFe12O19@SiO2 nanocomposites was identified by powder X-ray diffraction, scanning electronic microscopy, energy dispersive X-ray spectroscopy, vibrating sample magnetometer, thermal gravimetric anal. and Fourier transform IR spectroscopy. This method provided several benefits including easy work-up, the use solvent-free conditions, the low catalyst loading and the reusability of the catalyst. Recently the use of environmental and green catalysts which was easily recycled which received significant attention. Besides environmental advantages, such recoverable catalysts also provided a platform for heterogeneous catalysis, green chem. and environmentally benign protocols in the near future.
