N-Heterocyclic carbene palladium complex supported on ionic liquid-modified graphene oxide as an efficient and recyclable catalyst for Suzuki reaction

An N-Heterocyclic carbene palladium complex immobilized on graphene oxide (GO) with an ionic liquid framework (NHC-Pd/GO-IL) was synthesized by the modification of GO through a silylation reaction. The obtained catalyst displayed a high activity toward the Suzuki reaction in EtOH-H2O (1 : 1).
