A well-defined magnesium enolate initiator for the living and highly syndioselective polymerisation of methylmethacrylate.

The reaction of (BDI)MgiPr [BDI = HC(C(Me)=N-2,6-iPr2C6H3)2] with 2',4',6'-trimethylacetophenone in toluene affords the enolate complex [(BDI)Mg(mu-OC(=CH2)-2,4,6-Me3C6H2)]2 which is found to be an excellent initiator for the living, syndioselective (sigma r > 0.95) polymerisation of methyl methacrylate.

Discovery of a new family of chromium ethylene polymerisation catalysts using high throughput screening methodology.

Following a discovery that salicylaldimines bearing bulky ortho-phenoxy substituents and small imine substituents give very active chromium catalysts for ethylene polymerisation, High Throughput Screening (HTS) methodology has been employed to facilitate a further discovery of exceptionally active catalysts based on tridentate salicylaldimine ligands with bulky triptycenyl groups.
