Abstract

In the present investigation, an efficient and environmentally adopted synthesis of triaryl substituted imidazole in one-pot was reported. The multicomponent reaction between various aldehydes, benzil, benzoin, ammonium acetate and glycine under solvent free condition has been explained. Instead of using toxic reagents for the synthesis of heterocyclic compounds, Glycine has been selected as a green catalyst due to simple work-up procedure, shorter reaction time and high yield. The synthesized imidazole derivatives on further treatment with phosphorous oxychloride resulted in an organophosphorous containing N-heterocyclic compound (N-P) thus by altering acidic hydrogen of imidazole. Further, N-P was reacted with polyvinyl alcohol resulted into organophosphorous N-heterocyclic vinyl polymers. The synthesized vinyl polymers were characterized using, FTIR, NMR and Mass spectral studies. Results of the spectral studies were well supported the formation of the compounds. Thermal stability have also been studied using TGA.
