Abstract (en)

[origin: DE19549352A1] Compound of formula (I) is new: LnAmMXk (I) L = borato-benzene ligand of formula (II): R = H, 1-10C alkyl or 6-10C aryl, or two adjacent R groups can form a ring system; Y = H, 1-10C alkyl, 6-10C aryl, halogen, NR2<2>- or -PR2<2>; R<2> = halogen, 1-10C alkyl or 6-10C aryl; A = optionally substituted pi -ligand, eg. cyclopentadienyl, or optional adjacent substituents on the ring may combine to form another ring system; M = Group IIIb or Vb metal; X = H, 1-20 C alkyl, 1-10C alkoxy, 6-20 C aryl, 2-12C alkenyl, 7-40C arylalkyl, 7-40C alkylaryl, OH, halogen or NR2<2>; n = 1 - 2; m = 0 - 1; and k = 1 - 4, with the provision that the sum of n + m + k is 3 - 5. Also claimed are: (i) the preparation of (I); and (ii) use of cpds. (I) as catalyst components for the polymerisation of olefins.
