Suzuki reactions catalysed by a palladium(II) complex of a functionalized bis(imidazolium) ligand, Pd II (BIM), immobilized on Dowex 50 WX8 and Amberlite IR‐120 ion‐exchange resins as heterogeneous, recyclable and active catalysts are reported. The catalysts, Pd II (BIM)@Amberlite IR‐120 and Pd II (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 .
