Synthesis of double silylene-bridged binuclear metallocenes and their cooperation effect during ethylene polymerization and ethylene/1-hexene copolymerization

Novel double silylene‐bridged binuclear Group 4 metallocene complexes [(η5‐C5H5)MCl2]2[μ, μ‐(SiMe2)2 (η5‐RC5H2)2] [R = Me, M = Zr (1); R = allyl, M = Ti (2); R = allyl, M = Zr (3); R = nBu, M = Ti (5); R = Me3Si, M = Zr (6)] and [(η5‐CH3C5H4)ZrCl2]2[μ, μ‐(SiMe2)2 (η5‐allyl‐C5H2)2, (4)] were synthesi...
