We report the covalent support of functionalized nickel complexes on magnetic core-shell hybrid particles γ-Fe2O3/SiO2. Two completely different ways of connecting the particle with these nickel complexes were carried out. The first approach used the hydrosilylation method between the alkene substituted nickel-complex and a silane. In a second approach, the particles were connected with the complexes via click chemistry (copper catalyzed Huisgen 1,3-dipolar cycloaddition). For this purpose the nickel complexes were substituted with an alkyne moiety. The characterization methods transmission and scanning electron microscopies, energy dispersive X-ray diffraction, and FT-IR spectroscopy were employed to characterize the successful heterogenization of the nickel complexes.
