Abstract

Using Augustine’s method, a new heterogenized Ru(II)-N-heterocyclic carbene complex was prepared on Al2O3 support. The anchored catalyst was characterized by spectroscopic methods and was applied in the hydrogenation of different olefins, aldehydes and ketones. The hydrogenations were performed in aqueous medium on homogeneous and heterogenized complexes. The immobilized complex had a reasonable activity and selectivity at the same time it was possible to filter out from the reaction mixture and to recycle in several subsequent runs.

Keywords: Anchored Ru complexes, hydrogenations, enantio selective, catalyst.
