Abstract
The present invention provides novel ruthenium or osmium based complex structures with a unique combination of ligands comprising a Schiff-base type ligand, a N-heterocyclic carbene ligand and a CO ligand which can be prepared according to two different routes involving easily accessible starting materials and which represent excellent catalysts for hydrogenating unsaturated compounds, oligomers and polymers, in particular at unforeseeably low temperatures.
