•New SO3H-functionalized polyoxometalate-based ionic liquids were synthesized.•The resultant salts were characterized.•Catalytic activity of these ionic liquids were investigated in CC coupling.•Reusability and weight loosing of these heterogeneous catalyst were studied.
Different ionic liquids (ILs) with SO3H as functional group were achieved by combining SO3H-functionalized organic cations and polyoxometalates (POM). The obtained salts were characterized and their catalytic activities investigated in CC coupling between benzhydrol and aromatic compounds at neat conditions, including the effect of organic cations, influence of POMs, optimization of reaction conditions, and reusability of the catalyst. Furthermore, Recovery, reusability and activity of ILs as heterogeneous catalysts were studied at least four times.
