The reactions of chelating diboranes with PhCMe2Cl and related initiators were studied by variabletemperature NMR spectroscopy. Although thermally stable ion-pairs featuring weakly coodinating anions (WCA) are formed, isobutene polymerization is complicated by the tendency of these WCA to act as hindered bases toward Br√łnsted acidic chain ends. ¬© 2007 American Chemical Society.
