Title
Selective oxidation of alcohols with H2O2 catalyzed by long chain multi-SO3H functionalized heteropolyanion-based ionic liquids under solvent-free conditions
Abstract

•Two multi-SO3H functionalized heteropolyanion-based ionic liquids were prepared.•Ionic liquids exhibit high catalytic activities in selective oxidation of alcohols.•Oxidation was carried out with H2O2 aqueous as oxidant under solvent-free conditions.•Ionic liquids can be recovered and reused five times without loss in activities.

Two novel long chain multi-SO3H functionalized heteropolyanion-based ionic liquids were prepared and characterized. They as homogeneous catalysts showed high catalytic activity in selective oxidation of alcohols with 35% aqueous hydrogen peroxide under solvent-free conditions without adding any phase transfer catalyst. Two ionic liquids can be recovered readily and reused five times without any significant loss in their catalytic activities.
