We synthesized 3-(3-aminopropyl)-1-methylimidazolium bromide, [APMIm][Br], to functionalize graphene oxide (GO), which was used as a heterogeneous N-heterocyclic carbine (NHC) precursor (denoted GO-NHC). Then, Pd(OAc)2 was immobilized onto GO-NHC to form a Pd/NHC complex (denoted GO-NHC-Pd). The synthesized GO-NHC-Pd was fully characterized by FT-IR, ICP, and XPS. GO-NHC-Pd exhibited its excellent catalytic activity in Suzuki C-C coupling reaction. In addition, GO-NHC-Pd was reused in Suzuki reaction several times without a loss of its catalytic activity. |
