Monochlorotriazinyl‐β‐cyclodextrin Grafted on Graphene Oxide as an Attractive Green Heterogeneous Nanoreactor for Selective Oxidation Reaction with NBS in Water

Abstract

Graphene oxide supported monochlorotriazinyl‐β‐cyclodextrin (GO‐MCT‐ β‐CD) as a green nanoreactor was synthesized via a simple chemical bonding method and analyzed by XRD, FT‐IR, CHNS, FESEM and Raman spectroscopy. The prepared GO‐MCT‐β‐CD worked as a nanoreactor for the green oxidation reactions of benzyl alcohol derivatives with N‐bromo succinimide to their corresponding aldehydes under green conditions. Depending on the different substituents of various benzyl alcohols, good to excellent yields were obtained and no over‐oxidation was observed. It can be considered an attractive methodology due to the use of water in the presence of “solid metal‐free nanoreactor” as a green reaction system at the room temperature. Easy separation and excellent reusability of the catalyst were other advantages of this methodology.
