Abstract:
This invention relates to novel catalyst compositions based on Ruthenium- or Osmium-based complex catalysts of the Grubbs-Hoveyda, Grela or Zhan type and specific co-catalysts comprising at least one vinyl group, pref. ethyl vinyl ether, and to a process for selectively hydrogenating nitrile rubbers in the presence of such catalyst compositions, preferably with a preceding metathesis step using the same complex catalyst as in the hydrogenation step.

Claim (Index 1):
A selective hydrogenation of nitrile rubber comprising selectively hydrogenating nitrile rubber in the presence of a catalyst composition obtained by contacting a complex catalyst with at least one co-catalyst in a molar ratio of the complex catalyst to the co-catalyst of 1:30 to 1:100, wherein:\n the complex catalyst has the general formula (A) where\n M is ruthenium or osmium, \n X 1  and X 2  are identical or different ligands, \n L is an electron donating ligand, which can be linked or not linked with X 1  to form a cyclic structure, \n R 1  is hydrogen, alkyl, cycloalkyl, alkenyl, alkynyl, aryl or heteroaryl, \n R 2 , R 3 , R 4  and R 5  are identical or different and are each hydrogen or an organic or inorganic substituent, \n R 6  is H, alkyl, cycloalkyl, alkenyl, alkynyl, aryl, heteroaryl, \u2014C(\u2550O)R, \u2014C(\u2550O)OR, \u2014C(\u2550O)N(R) 2 , \u2014C(\u2550S)R, \u2014C(\u2550S)SR, \u2014C(\u2550S)OR, \u2014C(\u2550S)N(R) 2 , \u2014S(\u2550O) 2 N(R) 2 , \u2014S(\u2550O) 2 R, \u2014S(\u2550O)R, or a group containing either a C\u2550O or a C\u2550S structural element adjacent to a carbon atom which is bound to Y, \n N is 0 or 1, \n wherein if n=1, then the element \n shall mean that Y and (E) n  are linked either by a single bond or by a double bond, wherein\n (i) if Y and (E) n  are linked by a single bond, then Y is oxygen (O), sulfur (S), N\u2014R or P\u2014R, and\n E is CH 2 , or \n (ii) if Y and (E) n  are linked by a double bond, then\n Y is N or P, and \n E is CH, and \n wherein if n=0, then\n Y is oxygen (O), sulfur (S), N\u2014R or P\u2014R, and is directly linked by a single bond to the phenyl moiety depicted above in formula (A), and \n wherein in all above occurrences of general formula (A), R is hydrogen or alkyl, cycloalkyl, alkenyl, alkynyl, aryl or heteroaryl; and \n wherein the co-catalyst must contain at least one vinyl group, and has the general formula (1)\n CH 2 \u2550CRR\u2032\u2003\u2003(1) \n in which R and R\u2032 are identical or different and in the co-catalyst shall mean hydrogen, wherein R and R\u2032 must not both represent hydrogen, or\n OR 1  wherein shall mean alkyl, cycloalkyl, alkenyl, alkynyl, aryl, or heteroaryl, C(\u2550O)(R 2 ), \u2014C(\u2550O)N(R 2 ) 2 , \u2014[(CH 2 ) n \u2014X] m R 2 , \u2014[(CH 2 ) n \u2014X] m \u2014CH\u2550CH 2 , or \u2014(CH 2 ) p \u2014C(R 3 ) 2 R 4 , wherein\n X is identical or different and means oxygen (O) or NR 2  \n R 2  are identical or different and represent H, alkyl, cycloalkyl, alkenyl, alkynyl, aryl, or heteroaryl, \n R 3  are identical or different and represent C 1 -C 8  alkyl or \u2014(CH 2 ) n \u2014O\u2014CH\u2550CH 2 , \n R 4  represents (CH 2 ) p \u2014O\u2014CH\u2550CH 2 , \n n is 1 to 5, \n m is 1 to 10, \n p is 0 to 5, or \n \n where in the alternative, if R and R\u2032 both represent a group OR 1 , both R 1  may be linked to each other and together represent a divalent group \u2014(C(R 2 ) 2 ) o \u2014 with q being 2, 3 or 4 and R 2  being identical or different and having the above defined meanings, or \n SR 5 , SOR 5 , SO 2 R 5  wherein R 5  represents alkyl, cycloalkyl, alkenyl, alkynyl, aryl, or heteroaryl, or \n N(R 6 R 7 ), P(R 6 R 7 ) wherein R 6  and R 7  are identical or different and shall mean alkyl, cycloalkyl, alkenyl, alkynyl, aryl, heteroaryl, \u2014C(\u2550O)(R 2 ), or where in the alternative R 6  and R 7  may form together with such N or P atom to which they both are linked at the same time a saturated, unsaturated or aromatic cyclic structure with 4 to 7 carbon atoms in the cyclic structure wherein one, two or three of said carbon atoms can be replaced by a moiety selected from oxygen, sulfur, nitrogen, N\u2014R 8  or P\u2014R 8  wherein R 8  shall mean alkyl, cycloalkyl, alkenyl, alkynyl, aryl, or heteroaryl; or \n P(\u2550O)(OR 9 ) 2  in which R 9  are identical or different and shall mean alkyl, cycloalkyl, alkenyl, alkynyl, aryl, heteroaryl.
