Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Journal of Physics and Chemistry of Solids called Pumice-modified cellulose fiber: An environmentally benign solid state hybrid catalytic system for the synthesis of 2,4,5-triarylimidazole derivatives, Author is Maleki, Ali; Gharibi, Saideh; Valadi, Kobra; Taheri-Ledari, Reza, which mentions a compound: 484-47-9, SMILESS is C1(C2=CC=CC=C2)=NC(C3=CC=CC=C3)=C(C4=CC=CC=C4)N1, Molecular C21H16N2, Formula: C21H16N2.
An instrumental hybrid catalytic system comprising cellulose fiber and volcanic pumice powder, which was applied as a suitable organic-inorganic hybrid catalyst for the synthesis of 2,4,5-triarylimidazole derivatives was developed in this study. High reaction yields (97%) were obtained in short reaction times (20 min) using this catalytic system. In phys. terms, the high porosity of pumice provided an extremely high active surface area for electronic interactions among the components. Moreover, the most distinctive properties of this catalytic system were high biodegradability, simple separation of the catalyst, and good reusability. The natural pumicewas recovered easily using an external magnet and reused with no significant decline in the catalytic activity. The structural characteristics of this efficient catalytic system were assessed using various anal. methods.
