Abstract

A novel organic-inorganic hybrid nanomaterial was fabricated by anchoring an organic constituent possessing a 4,4â²-bipyridine framework to nano-silica (as an inorganic constituent). The nanomaterial, namely 1-(Si-pr)-[4,4â²-bipyridine]-1,1Ê¹-diium dihydrogen phosphate anchored to nano-silica (SPBDS), was characterized by EDS, elemental mapping, FE-SEM, FT-IR, XRD, and TG analyses. Thereafter, bis(pyrazolyl)methanes were successfully constructed through the solvent-free reaction of 3-methyl-1-phenyl-1H-pyrazol-5(4H)-one (2 eq.) and aryl aldehydes (1 eq.) using SPBDS. The catalyst was reusable nine times without a significant decrement in its performance.
