Imidazole-Functionalized Fe3O4/Chloro-Silane Core-Shell Nanoparticles: an Efficient Heterogeneous Organocatalyst for Esterification Reaction

Imidazole supported onto Fe 3 O 4 /Chloro-Silane core-shell nanoparticles was synthesized and characterized using different techniques including: SEM, XRD, TGA and FT-IR analyses. The prepared catalyst evaluated as an efficient heterogeneous organocatalyst for the esterification of carboxylic acids with alcohols in the presence of N,N’-dicyclohexylcarbodiimide as a coupling reagent under mild reaction conditions. This procedure presents a simple methodology and the efficient recyclability as well as reusability of the catalyst.
