摘要：

Addition of the strong organometallic Lewis acid B(C6F5)(3) to (eta(4)-butadiene)ZrCp2* (Cp*=eta(5)-pentamethylcyclopentadienyl) yields the open-chain metallocene-hydrocarbylborate-betaine complex 2. The novel betaine complex 2 is an active homogeneous single component metallocene Ziegler catalyst for a-olefin polymerization. (C) 1997 Elsevier Science S.A.
