Synthesis of heterobinuclear metallocenes containing bridging ansa-bis-η-cyclopentadienyl ligands †

Malcolm L. H. Green  and  Neil H. Popham  

Abstract

Binuclear metallocene derivatives have been prepared, exemplified by [Cl2(η-C5H5)Zr{µ-(η-C5H4)CMe2(η-C9H6)}Rh(CO)2], [Cl2(η-C5H5)Zr{µ-(η-C5H4)CMe2(η-C9H6)}Rh(PPh3)2], [Cl2(η-C5H5)Zr{µ-(η-C5H4)CMe2(η-C9H6)}Mn(CO)3], [Cl2(η-C5H5)Zr{µ-(η-C5H4)CMe2(η-C9H6)}Ru(CO)(η-C4H7)], [Fe{µ-(η-C5H4)CMe2(η-C9H6)Zr(η-C5H5)Cl2], [Cl2(η-C5H5)Zr{µ-(η-C5H4)CMe2(η-C9H6)}Co(η-C5Me5)], [Cl2(η-C5H5)Zr{µ-(η-C5H4)C(CH2)5(η-C9H6)}Zr(η-C5H5)Cl2], [Cl2(η-C5H5)Hf{µ-(η-C5H4)(CH2)5C(η-C9H6)}Hf(η-C5H5)Cl2]. The tris-η-cyclopentadienyl compounds [Zr{Me2C(η-C5H4)2(η-C5H4Me)Cl}] and the new η-indenyl compound [Zr{(4-ButC6H9)(η-C5H4)(η2-C9H6)}(η-C5H5)Cl] are also described. The activity of a selection of the binuclear compounds as co-catalysts for ethylene polymerisation has been demonstrated.
