摘要：
New chromocenes have been supported on silica and tested as catalyst in ethylene polymerisation. The synthesis of chromocenes by cyclopentadienyl exchange is reported. Ligand exchange reactions of cyclopentadienyl complexes with metallocenes or with cyclopentadienyl salt constitute a new ready reaction pathway to new substituted chromocenes. Effect of cyclopentadienyl basicity and/or steric hindrance on the coordination and reactivity of cyclopentadienyl ligands is reported.
