Abstract
The mesoporous zeolite BEA (MZB or BEA/MCM-41 composite) material with bimodal pore structure, acidity and surface area has been synthesized by using zeolite BEA as silica-alumina source. The material was characterized by various techniques such as powder SAXS/WAXS, N2 adsorption-desorption isotherm, NH3-TPD, ICP-OES, TGA-DTA, FT-IR, Pyridine IR, SEM, TEM, 27Al and 29Si NMR. Powder SAXS/WAXS showed the existence of well-structured microphase of zeolite BEA and mesophase of MCM-41 in the composite materials. In addition, the significant improvement in the catalytic properties of MZB material was investigated for the synthesis of various biologically active compounds through multi-component reactions (MCRs). The MZB material display excellent activity towards the synthesis of 2,4,5-triphenyl-1(H)-imidazoles and 1-benzyl-2,4,5-triphenyl-1H-imidazoles through MCRs in high yield within shorter reaction time and with low catalyst loading as compared to the microporous zeolite H-BEA. Solvent-free protocol makes the process environmentally benign and economically viable. The present protocol will serve as green tool and opens a new avenue in the area of environmentally benign synthesis of biologically active drug like molecules.
