Journal ArticleDOI
Polymerisation of ethene by the novel titanium complex [Ti(Me3SiNCH2CH2NSiMe3)Cl2]; a metallocene analogue
TL;DR: In this paper, the reaction of the trimethylsilylated diamine ligand (Me3Si)NHCH2CH2NH(SiMe3) with titanium(IV) precursors affords the novel distorted-tetrahedral complex [Ti(Me 3SiNCH 2CH2NSiMe3]Cl2] which, when activated by methylaluminoxane, is an active ethene polymerisation catalyst.
Journal ArticleDOI
N-alkyl-2-pyridylmethanimines as tuneable alternatives to bipyridine ligands in copper mediated atom transfer radical cyclisation
Andrew J. Clark,David J. Duncalf,Robert P. Filik,David M. Haddleton,Gerard Hugh Thomas,Hathaichanuk Wongtap +5 more
TL;DR: Copper halide complexes of N-alkyl-2-pyridylmethanimines catalyse atom transfer radical cyclisation reactions of activated ( 6a-b ) and unactivated α-haloallylacetamides ( 9 ) at room temperature as discussed by the authors.
Journal ArticleDOI
[N‐Alkyl‐(2‐pyridyl)methanimine]copper(I) Complexes: Characterisation and Application as Catalysts for Atom‐Transfer Polymerisation
David M. Haddleton,David J. Duncalf,Dax Kukulj,Martin C. Crossman,Stuart G. Jackson,Stefan Antonius Franciscus Bon,Andrew J. Clark,Andrew J. Shooter +7 more
TL;DR: In this paper, the synthesis and characterisation of a series of bis(imine)copper(I) complexes and their use in atom-transfer polymerisation of methyl methacrylate is described.
Journal ArticleDOI
Atom transfer polymerisation of methyl methacrylate: use of chiral aryl/alkyl pyridylmethanimine ligands; with copper(I) bromide and as structurally characterised chiral copper(I) complexes
David M. Haddleton,David J. Duncalf,Dax Kukulj,Alex M. Heming,Andrew J. Shooter,Andrew J. Clark +5 more
TL;DR: The use of chiral catalysts in the living radical polymerisation of methyl methacrylate via atom transfer polymerisation (ATP) has been investigated in an effort to control the stereochemistry of the polymer backbone as discussed by the authors.
Journal ArticleDOI
Synthesis and Mechanism of Formation of Syndiotactic Polystyrene Using a (tert-Butylcyclopentadienyl)titanium Complex
David J. Duncalf,Harvey J. Wade,Carl Waterson,Peter J. Derrick,David M. Haddleton,Andrew McCamley +5 more
TL;DR: Polymerization of styrene in the presence of [Ti(η5-C5H4tBu)Cl3]-methylaluminoxane has been investigated as discussed by the authors.
