ABSTRACT:
There is disclosed a new boron-containing compounds such as bis-(pentafluorophenyl)borane, (C.sub.6 F.sub.5).sub.2 BH and related compounds and a method for producing the compounds. The new borane is suitable for use as a hydroboration reagent for the rapid hydroboration of alkenes and alkynes. The borane is also suitable for use as a hydroboration reagent to produce useful boron reagents that can be used in Ziegler-Natta homogeneous olefin polymerization catalyst systems. Specifically, the borane reagent can be used to produce Cp.sub.2 Zr{.eta..sup.3 -CH(C.sub.6 H.sub.5)[(.mu.-H)B(C.sub.6 F.sub.5).sub.2 ]}, which exhibits an efficacy for polymerization of ethylene.
