Abstract
The fully characterised group 3A and lanthanoid metal complexes [M(η-C5H4R)2Me]2(M;Y or Er, RH, Me, or SiMe3, and MYb, RH or Me) and [M(η-C5H4R)2Me2AlMe2](MY, Er, Ho, or Yb RH or Me, and MY, RSiMe3) are active homogenous ethylene polymerisation catalysts; they show an intramolecular deactivation process involving abstraction of a cyclopentadinyl hydrogen which is completely suppressed with peralkylated derivatives.Keywords
