摘要：

The reactions of chelating diboranes with PhCMe2Cl and related initiators were studied by variable-temperature 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 Bronsted acidic chain ends.
