Zirconium complexes of cyclopenta[b]pyridine: synthesis, structure, and olefin polymerization catalysis

By treatment of Cp*ZrCl3 with the lithium salt of cyclopenta[b]pyridine (LiCpPy) in toluene, the unsymmetrical complex Cp*(η5-CpPy)ZrCl2 was prepared in 32% yield. On the evidence of X-ray crystal structure analysis, the bifunctional CpPy ligand coordinates Zr in an η5-manner rather than via nitrogen. Cyclopenta[b]pyridine turned out to react with Zr(NMe2)4 in toluene to form mono-cyclopentadienyl complex (η5-CpPy)Zr(NMe2)3(Me2NH) in 70% yield. The polymerization of ethylene and the copolymerization of ethylene with 1-hexene or propene catalyzed by Cp*(η5-CpPy)ZrCl2 activated with MAO was studied in detail.
