Abstract:
Catalyst compositions based on Ruthenium- or Osmium-based complex catalysts and specific co-catalysts are provided for selectively hydrogenating nitrile rubbers in the presence of such catalyst compositions.

Claim (Index 15):
The process for hydrogenating nitrile rubber according to  claim 9 , wherein the complex catalyst is one of the general formulae (E), (F), and (G) in which\n M is ruthenium, X 1  and X 1  are both halogen, R 1  and R 2  are identical or different and are five- or six-membered monocyclic groups having from 1 to 4, heteroatoms or bicyclic or polycyclic structures made up of 2, 3, 4 or 5 five- or six-membered monocyclic groups of this type, where all the above-mentioned groups may in each case be substituted by one or more moieties selected from the group consisting of alkyl, cycloalkyl, alkoxy, halogen, aryl, or heteroaryl, Z 1  and Z 2  are identical or different and five- or six-membered monocyclic groups having from 1 to 4, heteroatoms or bicyclic or polycyclic structures made up of 2, 3, 4 or 5 five- or six-membered monocyclic groups of this type, where all these abovementioned groups may in each case optionally be substituted by one or more alkyl, cycloalkyl, alkoxy, halogen, aryl, or heteroaryl, radicals which may in turn each be substituted by one or more moieties selected from the group consisting of halogen, C 1 -C 5 -alkyl, C 1 -C 5 -alkoxy and phenyl, R 21  and R 22  are identical or different and are each C 1 -C 30 -alkyl C 3 -C 20 -cycloalkyl, C 2 -C 20 -alkenyl, C 2 -C 20 -alkynyl, C 6 -C 24 -aryl, C 1 -C 20 -carboxylate, C 1 -C 20 -alkoxy, C 2 -C 20 -alkenyloxy, C 2 -C 20 -alkynyloxy, C 6 -C 24 -aryloxy, C 2 -C 20 -alkoxycarbonyl, C 1 -C 30 -alkylamino, C 1 -C 30 -alkylthio, C 6 -C 24 -arylthio, C 1 -C 20 -alkylsulphonyl, C 1 -C 20 -alkylsulphinyl, and L has a structure of the above-described general formula (IIa) or (IIb.
