Palladium supported on pyrrole functionalized hypercrosslinked polymer: Synthesis and its catalytic evaluations towards Suzuki-Miyaura coupling reactions in aqueous media

•A novel palladium catalyst immobilized on hypercrosslinked polymer was prepared via a facile Scholl coupling method.•The obtained catalyst exhibited high catalytic efficiency towards Suzuki reactions in aqueous media.•Due to the Pd coordination on the polymer surface, the trace metal leaching was achieved.•This study provides a simple approach for supporting palladium on the surface of such functional polymers.
