Abstract

Hydrosilylatable compositions employ ruthenium compounds with a ligand sphere comprising at least two independent carbon π-bonded ligands, at least one of these ligands being selected from the group consisting of η6-bonded arene ligands, η6-bonded triene ligands, η4-bonded 1,5-cyclooctadiene ligands and η4-bonded 1,3,5-cyclooctatriene ligands as a hydrosilylation catalyst.
