The development of silicate mesoporous materials is currently an area of extensive research because of their potential application in areas such as catalysis, adsorption, drug delivery, sensor technology and chromatography [1]. In this paper, a Ni(II) complex of N2,N6-bis(3-(triethoxysilyl)propyl)pyridine-2,6-dicarboxamide [2] has been immobilized on MCM-41 to prepare a heterogeneous catalyst. The MCM-41@PDCA-Ni has been characterized by different techniques such as FT-IR, low angle powder XRD, TGA, SEM, TEM, MP-AES and N2 sorption studies and its application has been tested in the synthesis of bezimidazoles and quinazolinones through the coupling of substituted benzaldehyde with o-phenylenediamine and anthranilamide respectively. The prepared catalyst showed tolerance towards both electron-withdrawing and electron-donating functional group. High yield and ease in recovery by simple filtration for upto five times without any considerable loss in catalytic efficiency are the main advantages of the catalyst.
