Magnetic Nanoparticle Supported Second Generation Hoveyda–Grubbs Catalyst for Metathesis of Unsaturated Fatty Acid Esters

Authors


Abstract

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.
