| Abstract: | The compounds M{(CH2)4C(η-C5H4)2}(η-C5H5)Cl] (M=Zr*, Hf), M{(CH2)4C(η-C5H4)2}(η-C5H5)Me] (M=Zr, Hf), (η-C5H5)MCl2{(CH2)4C(η-C5H4)2}MCl2(η-C5H5)] (M=Zr, Hf), (η-C5H5)ZrCl2{(CH2)4C(η-C5H4)(η-C9H6)}ZrCl2(η-C5H5)], (η-C5H5)MMe2{(CH2)4C(η-C5H4)2}MMe2(η-C5H5)] (M=Zr, Hf), (η-C5H5)ZrCl2{(CH2)4C(η-C5H4)2}HfCl2(η-C5H5)], (η-C5H5)MCl2{(CH2)4C(η-C5H4)2}Rh(η-C8H12)] (M=Zr*, Hf), (η-C5H5)ZrCl2{(CH2)4C(η-C5H4)2}TiCl3], (η-C5H5)ZrMe2{(CH2)4C(η-C5H4)2}HfMe2(η-C5H5)], (η-C5H5)MMe2{(CH2)4C(η-C5H4)2}Rh(η-C8H12)] (M=Zr*, Hf) have been prepared and characterised. * indicates the crystal structure has been determined. Their catalytic properties for ethene and propene polymerisation have been explored. |
