immobilization of a palladium(ii) bis(imidazolium) complex onto graphene oxide by noncovalent interactions: an efficient and recyclable catalyst for suzuki–miyaura reaction

In this research, the suzuki–miyaura coupling reaction catalyzed by a palladium(ii) complex containing bis(imidazolium) ligand, pdii(bim), immobilized on graphene oxide (go) as heterogeneous, recyclable and active catalyst is reported. the catalyst, pdii(bim)@go, was characterized by ft-ir, diffuse reflectance uv–vis spectroscopy, icp, field emission scanning electron microscopy, energy-dispersive x-ray analysis, and elemental analysis. it was demonstrated that the go-supported palladium(ii) complex can act as an efficient catalyst and is reusable several times without a significant loss of their catalytic activity.
