A new, heterogenized Ru(II)-N-heterocyclic carbene complex was prepared via the method developed by Augustine. The anchored catalyst was characterized by spectros-copic methods and was applied in the hydrogenation of different olefins, aldehydes and ketones. The hydrogenations were performed both in alcohol and in aqueous media on homogeneous and heterogenized complexes. The immobilized complex had a reasonable activity in both conditions and at the same time it was possible to filter out from the reaction mixture and to recycle in several subsequent runs.
