PROCESS FOR PRODUCTION OF BIS-(PENTAFLUOROPHENYL)BORANE AND USE THEREOF FOR PRODUCTION OF BASE FREE ZWITTERIONIC HOMOGENEOUS ZIEGLER-NATTA OLEFIN POLYMERIZATION CATALYSTS

摘要

There is disclosed a new boron-containing compounds such as bis-(pentafluorophenyl)borane, (C6F5)2BH 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 Cp2Zr{?3-CH(C6H5)¢(.mu.-H)B(C6F5)2!}, which exhibits an efficacy for polymerization of ethylene.
