Name: 2,4,5-Triphenylimidazole. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: 2,4,5-Triphenylimidazole, is researched, Molecular C21H16N2, CAS is 484-47-9, about Sulfonated Fe3O4@PVA superparamagnetic nanostructure: design, in-situ preparation, characterization and application in the synthesis of imidazoles as a highly efficient organic-inorganic Bronsted acid catalyst. Author is Maleki, Ali; Rahimi, Jamal; Valadi, Kobra.
A new approach for in-situ preparation of Fe3O4@PVA nanostructure as well as its sulfonation was investigated. Then, the functional group of the prepared nanocatalyst was characterized by Fourier transform IR (FT-IR) spectroscopy. The size and morphol. of the nanoparticles were tested by using SEM images. The presence of constructive elements in the nanocomposites was confirmed by energy dispersive X-ray (EDX) anal. To better insight, the structure and magnetic properties of the prepared nanostructure were studied by X-ray diffraction (XRD) pattern and vibrating sample magnetometer (VSM) anal. Thermal stability and weight loss for the nanostructure composition at each step of weight change were screened by thermogravimetric anal. (TGA). Finally, the prepared nanocomposite structure was confirmed by transmission electron microscope (TEM) image. Then, for the first time, Fe3O4@PVA sulfonic acid-based superparamagnetic nanocatalyst was studied for the synthesis of 2,4,5-triarylimidazoles I (R = Ph, 2,4-dichlorophenyl, 2-thienyl, etc.) via a one-pot three-component condensation reaction starting from ammonium acetate, aldehydes RCHO and benzil or benzoin. Due to high magnetic property of the catalyst, it was easily recyclable by a magnet at least for ten runs without any significant reduction in the catalytic activity.
Although many compounds look similar to this compound(484-47-9)Name: 2,4,5-Triphenylimidazole, numerous studies have shown that this compound(SMILES:C1(C2=CC=CC=C2)=NC(C3=CC=CC=C3)=C(C4=CC=CC=C4)N1), has unique advantages.
