DESCRIPTION:
BRIEF SUMMARY
This application claims priority from PCT international application 96/05715 filed Dec. 19, 1996 and from Federal Republic of Germany 19548146.1 filed Dec. 21, 1995.
The present invention relates to metal complexes of the formulae (I) and (I') which are suitable for the oligomerization and polymerization of olefinically unsaturated compounds and for the copolymerization thereof with carbon monoxide ##STR2## where M is a metal from sub-group eight of the Periodic Table of the Elements, consisting of hydrogen, C.sub.1 - to C.sub.30 -organocarbon radicals and C.sub.3 - to C.sub.30 -organosilicon radicals, and C.sub.1 - to C.sub.30 -organocarbon radicals and C.sub.3 - to C.sub.30 -organosilicon radicals, polymerization of olefinically unsaturated compounds and the copolymerization thereof with carbon monoxide, comprising, as active constituents, ##STR3## or a metal complex of the formula (I') ##STR4## where M is a metal from sub-group eight of the Periodic Table of the Elements, consisting of hydrogen, C.sub.1 - to C.sub.30 -organocarbon radicals and C.sub.3 - to C.sub.30 -organosilicon radicals, and C.sub.1 - to C.sub.30 -organocarbon radicals and C.sub.3 - to C.sub.30 -organosilicon radicals, and
The present invention furthermore relates to a process for the preparation of metal complexes of the formula (I) ##STR5## by reacting a halometal complex of the metal with a tris(pyrazolyl)borate anion of the formula (II) ##STR6## or with a bis(pyrazolyl)borate anion of the formula (II') ##STR7## where, in (I), (I'), (II) or (II'), M is a metal from sub-group eight of the Periodic Table of the Elements, thallium, consisting of hydrogen, C.sub.1 - to C.sub.30 -organocarbon radicals and C.sub.3 - to C.sub.30 -organosilicon radicals, C.sub.1 - to C.sub.30 -organocarbon radicals and C.sub.3 - to C.sub.30 -organosilicon radicals, and unsaturated compounds and of copolymers of olefinically unsaturated compounds and carbon monoxide by polymerizing the monomers at from 0 to 300.degree. C. and from 1 to 500,000 kPa in the presence of a metal complex of the formula (I) ##STR8## where M is a metal from sub-group eight of the Periodic Table of the Elements, consisting of hydrogen, C.sub.1 - to C.sub.30 -organocarbon radicals and C.sub.3 - to C.sub.30 -organosilicon radicals, and C.sub.1 - to C.sub.30 -organocarbon radicals and C.sub.3 - to C.sub.30 -organosilicon radicals, unsaturated compounds and of copolymers of olefinically unsaturated compounds and carbon monoxide by polymerizing the monomers at from 0 to 300.degree. C. and from 1 to 500,000 kPa in the presence of a catalyst system comprising, as active constituents, ##STR9## where M is a metal from sub-group eight of the Periodic Table of the elements, consisting of hydrogen, C.sub.1 - to C.sub.30 -organocarbon radicals and C.sub.3 - to C30-organosilicon radicals, and C.sub.1 - to C.sub.30 -organocarbon radicals and C.sub.3 - to C.sub.3 --organosilicon radicals, and
The present invention furthermore relates to the use of a metal complex of the formulae (I) and (I') as claimed in claim 1 as catalyst for the preparation of oligomers and polymers of olefinically unsaturated compounds and for the preparation of copolymers of olefinically unsaturated compounds and carbon monoxide, and to the use of a catalyst system as claimed in claim 4 for the preparation of oligomers and polymers of olefinically unsaturated compounds and for the preparation of copolymers of olefinically unsaturated compounds and carbon monoxide.
Metal complexes of metals from sub-group eight of the Periodic Table of the Elements have hitherto, such as nickel, been used in olefin oligomerizations (W. Keim, Angew. Chem. (1990), pages 251 ff) or in olefin-carbon monoxide copolymerizations, palladium (E. Drent et al., in "Ziegler-Natta Catalysts", G. Fink, R. Muhlhaupt, H. H. Brintzinger (editors), Springer Verlag, Berlin (1995), pages 482 ff) or nickel (U.S. Pat. No. 3,984,388; U.S. Pat. No. 5,214,126).
However, none of the metal complexes or catalysts employed was free from disadvantages; either they were com
