Direct Observation of the Structural Isomerization of a Cationic Group 4 Ziegler−Natta Insertion Product

Abstract

An experimental model that allows for direct observation of a structural isomerization that is relevant to the group 4 metal-mediated Ziegler-Natta polymerization of alpha-olefins is presented. More specifically, several features of this system are consistent with current theories presented for chain epimerization that occurs during propene polymerization.
