Magnetic Hybrid Materials based on Co/C Nanoparticles and their Use in Catalysis

In this thesis, various polymers were introduced to Co/C nanoparticles followed by the immobilization of Pd nanoparticles or chelating ligands. They were employed in a great variety of Pd-catalzed hydrogenations, as well as C-C or C-heteroatom coupling reactions. Even a kinetic resolution based on Tsuji-Trost chemistry was performed. Thereby, the excellent magnetization of unfunctionalized Co/C NPs allowed a fast and easy separation of the introduced hybrid materials by an external magnetic field. The use of the polymers, additionally, enabled not only high Pd loadings, but also a good dispersibility, especially in polar solvents
