- Abstract
- Graphene oxide (GO) was functionalized with a N-heterocyclic carbene (NHC) precursor, 3-(3-aminopropy1)-1-methylimidazolium bromide ([APMIm][Br]) for the immobilization of palladium catalyst. The GO-supported NHC precursor (IMGO) formed a stable complex with Pd(OAc)(2) (GO-NHC-Pd), which showed excellent catalytic activity and fast reaction kinetics in the aqueous-phase Suzuki reaction of aryl bromides and chlorides at relatively mild conditions (1 h at 50 degrees C). The GO-NHC-Pd catalyst was reused several times without any loss of its catalytic activity in the Suzuki reaction of aryl bromide. (C) 2014 Elsevier Ltd. All rights reserved.
