Claim:
Compounds of the formula (I) where M is a metal of transition group III, IV, V or VI of the Periodic Table of the Elements, R 1 , R 2 , R 3 , R 4 , R 5 , R 6 are identical or different and are each a hydrogen atom, a halogen atom or Si(R 10 ) 3 , where the radicals R 10 are identical or different and are each a hydrogen atom or a C 1 –C 40 group, or R 1 , R 2 , R 3 , R 4 , R 5 , R 6 are identical or different and are each a C 1 –C 30 group, or two or more radicals R 1 and/or two or more radicals R 2 to R 6 can be joined to one another in such a way that the radicals R 1 or R 2 to R 6 and R 10 and the atoms connecting them form a C 4 –C 24 ring system which may in turn be substituted, and the radicals R 100 are identical or different and can each be a C 1 –C 40 group, and n is an integer from 1 to 4, and m is an integer from 0 to 4, and i is an integer from 1 to 100, and the radicals X can be identical or different and are each a hydrogen atom, a C 1 –C 10 -hydrocarbon group, or OR 9 , SR 9 , OSiR 3 9 , SiR 3 9 , PR 2 9 or NR 2 9 , where R 9 is a halogen atom, a C 1 –C 10 -alkyl group, a halogenated C 1 –C 10 -alkyl group, a C 6 –C 20 -aryl group or a halogenated C 6 –C 20 -aryl group, or the radicals L are each a toluenesulphonyl, trifluoroacetyl, trifluoracetoxyl, trifluoromethanesulphonyl, nonafluorobutanesulphonyl or 2,2,2-trifluoromethanesulphonyl group.
