Abstract:
A catalyst of the general formula I ##STR8## where M is a metal selected from the group consisting of titanium, zirconium, hafnium, vanadium, niobium, tantalum, chromium, molybdenum, tungsten, manganese and rhenium,L.sup.1 is an amine oxide ligand of the formula II, a phosphine oxide or arsine oxide ligand of the formula III, a pyridine N-oxide ligand of the formula VII or a pyridine ligand of the formula VIII ##STR9## where R.sup.1 to R.sup.3 are identical or different C.sub.1 -C.sub.30 -alkyl, C.sub.7 -C.sub.30 -aralkyl or C.sub.6 -C.sub.30 -aryl radicals which optionally contain ether oxygen atoms, carbonyl groups, hydroxyl groups, alkoxy groups, carboxyl groups, cyano groups, carboxylic ester groups, sulfo groups, phosphonic acid groups, nitro groups, halogen atoms and/or unsubstituted or C.sub.1 -C.sub.4 -alkyl-substituted amino groups as functional groups, where at least one of the radicals R.sup.1 to R.sup.3 has to have at least 11 carbon atoms and the two other radicals can be linked to form a ring, andR.sup.4 to R.sup.6 are identical or different C.sub.4 -C.sub.30 -alkyl, C.sub.7 -C.sub.30 -aralkyl or C.sub.10 -C.sub.30 -aryl radicals which optionally contain ether oxygen atoms, carbonyl groups, hydroxyl groups, alkoxy groups, carboxyl groups, cyano groups, carboxylic ester groups, sulfo groups, phosphonic acid groups, nitro groups, halogen atoms and/or unsubstituted or C.sub.1 -C.sub.4 -alkyl-substituted amino groups as functional groups, andR.sup.11 to R.sup.15 are, independently of one another, hydrogen or identical or different C.sub.1 -C.sub.30 -alkyl radicals, C.sub.7 -C.sub.30 -aralkyl radicals, C.sub.6 -C.sub.30 -aryl radicals, C.sub.1 -C.sub.30 -alkoxy groups, C.sub.7 -C.sub.30 -aralkoxy groups, C.sub.6 -C.sub.30 -aryloxy groups or dihydrocarbylamino groups having identical or different C.sub.1 -C.sub.30 -alkyl radicals, C.sub.7 -C.sub.30 -aralkyl radicals and/or C.sub.6 -C.sub.30 -aryl radicals as hydrocarbyl radicals which optionally contain ether oxygen atoms, carbonyl groups, hydroxyl groups, alkoxy groups, carboxyl groups, cyano groups, carboxylic ester groups, sulfo groups, phosphonic acid groups, nitro groups, halogen atoms and/or unsubstituted or C.sub.1 -C.sub.4 -alkyl-substituted amino groups as functional groups, where at least one of the radicals R.sup.11 or R.sup.15 has to be hydrogen, at least one of the radicals R.sup.11 to R.sup.15 being a long-chain linear or branched alkyl radical having at least 8 carbon atoms and the remaining radicals R.sup.11 to R.sup.15 are optionally linked in pairs to form rings,L.sup.2 is an auxiliary ligand selected from the group consisting of oxo, halides, pseudohalides, carboxylates, phenoxides, alkoxides, enolates, ketones, ethers, amines, amides, urea, urea derivatives and water or a further ligand L.sup.1 or a free coordination site,X is oxo oxygen or an unsubstituted or C.sub.1 -C.sub.4 -alkyl-substituted imido ligand,Z is phosphorous or arsenic,m is 1 or 2 andn is 1, 2 or 3.
