An Efficient Halometallate Ionic Liquid Functionalized Mesoporous ZSM-5 for the Reduction of Carbon-Carbon Multiple Bonds

Abstract

Transition metal containing halometallate ionic liquids (ILs) based economical catalysts have been developed for the selective reduction of carbon-carbon multiple bonds with hydrazine hydrate in ethanol under a mild reaction condition. Further, halometallate ILs have been tethered to the surface of mesoporous ZSM-5. Mn based halometallate IL tethered to the surface of mesoporous ZSM-5 exhibits the best activity in this study than the parent halometallate ILs. It exhibits efficient recyclability with no appreciable loss in the catalytic activity even after five recycles. In order to establish the reaction mechanism, ILs-hydrazine complexes have been prepared and investigated for the reduction reaction. The structure-activity relationship is established by their catalytic activities, physicochemical characterizations, ILs-hydrazine complex formation, and probe reactions. The catalyst also exhibits excellent activity in the reduction of alkynes to alkanes. The present catalytic process demonstrates several key advantages such as a mild and convenient reaction condition, low substrate to hydrazine ratio, reusability, and cost-effectiveness of the catalyst.
