Despite the well-established use of organomagnesium reagents, research into the chemistry of the alkaline earth metals has received an increase in popularity over the last two decades, largely due to their applications as reagents and catalysts. Recently, sterically-demanding A-donor ligands have become more popular because of their ability to provide stable metal-donor interactions and achieve kinetic stabilisation of the complex by crowding the metal centre. Furthermore, the isolation of subvalent magnesium and calcium complexes which challenged established knowledge of the metals prompted further investigations into their stabilisation in low oxidation states.

Polylactones are biodegradable polymers which may be used as alternatives to conventional plastics and have shown promise in novel medical applications. Industrial production of polylactones requires the use of a catalyst. The work described herein is directed toward the development of novel cationic magnesium-based lactone-polymerization catalysts. These cationic species are produced by alkide abstraction from a neutral precursor; a strategy which has seen only preliminary exploration in the context of lactone polymerization. The target catalyst system features a neutral phosphinimine-derivative ligand structure which was developed and produced specifically for the purpose of lactone polymerization catalysis. Target complexes were obtained by reaction of neutral alkylmagnesium precursors with protonated ligand derivatives. Syntheses and characterization of novel species are described herein. These catalysts are very active in the polymerization of 6-caprolactone, generating high molecular weight polymers in mere minutes under mild conditions. A preliminary study of polymerization catalysis is also reported. / xxiii, 126 leaves ; 29 cm
