The Hoveyda–Grubbs catalyst has been successfully immobilized on surface‐modified magnetic nanoparticles with a loading amount of 0.28 mmol ruthenium/g (magnetic support). The supported catalysts were active for the self‐metathesis of methyl oleate and macro‐monomer in a quantitative conversion, respectively. In addition, the catalyst can be easily separated by using a magnet and reused several times with sustained activity.
