Abstract

Back Cover: Highly isospecific polymerization of silyl-protected ω-alkenols, using a combination of [OSSO]-type bis(phenolato) dichloro zirconium(IV) complex and dMAO as the precatalyst and the activator, respectively, is established. This method represents the first example for a stereoselective polymerization of polar functional α-olefins ([mmmm] > 95%). Subsequently, the obtained terminal siloxy-substituted isotactic polymer could be readily transformed by a macromolecular desilylation/acetylation reaction sequence to afford the corresponding terminal acetyl-enriched polymer. Further details can be found in the article by Y. Saito, N. Nakata,* and A. Ishii* on page 969.

Keywords: [OSSO]-type ligands; isospecific polymerization; polar monomers; post-metallocene; zirconium.
