Abstract
A novel nanomaterial namely Si-propyl-functionalized 4,4′-bipyridine-1,1ʹ-diium bisulfate tetrachloroferrate anchored to rice husk-derived nano-silica (PBBTRS) was fabricated, and analyses involving EDS (energy-dispersive X-ray spectroscopy), elemental mapping, FE-SEM (field emission scanning electron microscopy), XRD (X-ray diffraction), FT-IR, Raman and inductively coupled plasma-optical emission spectroscopy (ICP-OES) were utilized to corroborate its structure. Thereafter, PBBTRS was applied as a highly efficacious, recoverable and dual-functional catalyst for the construction of N,N′-alkylidene bisamides from aryl aldehydes and primary amides under solvent-free conditions. A valuable improvement in this methodology is performing the reaction under mild conditions (60 °C).
