    Abstract: A new class of olefin dimerization catalysts and an efficient method for their preparation is disclosed. B (C.sub.6 F.sub.5).sub.3 reacts quantitatively with Group 4 metallocene type catalysts to yield highly reactive cationic complexes as follows:(L.sub.2 MR.sup.2).sup.+ X.sup.- whereL=R.sub.2 (C.sub.5 H.sub.3); R=CR'.sub.3 ; R.sup.2 =alkyl group (C=1.ltoreq.20);M=Ti, Zr, Hf;X.sup.- =RB(C.sub.6 F.sub.5).sub.3.sup.-, or methylalumoxane.These complexes are potent catalysts and may be used in the dimerization of .alpha.-olefins.

    Abstract: The synthesis, and use as precatalysts of chiral organozirconium complexes for olefin polymerization are disclosed, having the structure (C.sub.5 R'.sub.4-x R*.sub.x) A (C.sub.5 R".sub.4-y R"'.sub.y) M Q.sub.p, where x and y represent the number of unsubstituted locations on the cyclopentadienyl ring; R', R", R"', and R* represent substituted and unsubstituted alkyl groups having 1-30 carbon atoms and R* is a chiral ligand; A is a fragment containing a Group 13, 14, 15, or 16 element of the Periodic Table; M is a Group 3, 4, or 5 metal of the Periodic Table; and Q is a hydrocarbyl radical, or halogen radical, with 3.ltoreq.p.ltoreq.o. Related complexes may be prepared by alkylation of the corresponding dichorides. In the presence of methylalumoxane or triarylborane cocatalysts, these complexes form "cation-like" species which are highly active for olefin polymerization. In combination with a Lewis acid cocatalyst, propylene or other .alpha.-olefin polymerization can be effected with very high efficiency and isospecificity.
