Synthesis and catalytic properties of ansa-binuclear metallocenes of the Group IV transition metals
摘要:
The new ansa-bridged mono- and bi-nuclear Group IV metallocenes, {Zr[X(eta-C5H4)(2)](eta-C5H5)Cl} (where, X = SiMe(2) (1), CMe(2)CMe(2) (2)), {[(eta-C5H5)HfCl2][mu-eta-C5H4-(SiMe(2))-eta-C5H4][(eta-C5H5)HfCl2]} (3). {[(eta-C5H5)ZrCl2][mu-eta-C5H4(SiMe(2)CH(2)CH(2)SiMe(2))-eta-C5H4][(eta-C5H5)ZrCl2]} (4), {[(eta-C5H5)ZrCl2][mu-eta-C5H4-(SiMe(2))-eta-C9H6][(eta-C5H5)ZrCl2]} (5), {[(eta-C5H5)ZrCl2][mu-eta-C9H6-(SiMe(2))-eta-C9H6][(eta-C5H5)ZrCl2]} (6), {[(eta-C5H5)ZrCl2][mu-eta-C5H4-(SiMe(2))-eta-C5H4][(eta-C5H5)MCl(2)]}, M = Hf (7) or Ti (8), {[(eta-C5H5)ZrCl2][mu-eta-C5H4-(SiMe(2))-eta-C5H4][(eta-C(5)Me(5))TiCl2]} (9) and {[(eta-C5H5)ZrCl2][mu-eta-C5H4(SiMe(2))-eta-C5H4][TiCl3]} (10) an described. These compounds in the presence of methylaluminoxane are catalysts for the polymerisation of ethene and propene.
