Abstract
- Suzuki reactions catalysed by a palladium(II) complex of a functionalized bis(imidazolium) ligand, PdII(BIM), immobilized on Dowex 50 WX8 and Amberlite IR-120 ion-exchange resins as heterogeneous, recyclable and active catalysts are reported. The catalysts, PdII(BIM)@Amberlite IR-120 and PdII(BIM)@Dowex 50 WX8, were characterized using Fourier transform infrared and diffuse-reflectance UV–visible spectroscopies and scanning electron microscopy. These heterogeneous catalysts are oxygen-insensitive and air- and moisture-stable in CC coupling reactions, and are reusable several times without significant loss of their catalytic activity.
