Abstract

The structural isomer of a potentially very active Ziegler–Natta olefin polymerization catalyst 1, is one of the final products in the reaction of [Cp₂ZrMe₂] with the highly electrophilic borane HB(C₆F₅)₂. The most unusual structural feature of 1 is a pentacoordinate carbon atom. Interestingly, 1 is completely unreactive towards ethylene under ambient conditions. (Figure Presented.)
