Tacticity tactics: The dinuclear bis(enolate) complex 1, when activated with [PhNHMe2][B(C6F5)4], is an effective initiator of living methyl methacrylate polymerization, providing partially syndiotactic poly(methyl methacrylate) with a narrow molecular-weight distribution. Mechanistic studies showed that 1 is transformed into a cationic enolate complex and this dinuclear species is involved in propagation.
