The nature of oxygen exchange in ZrW2O8 revealed by two-dimensional solid-state O-17 NMR
Journal Article
Hampson, M., Hodgkinson, P., Evans, J., Harris, R., King, I., Allen, S., & Fayon, F. (online). The nature of oxygen exchange in ZrW2O8 revealed by two-dimensional solid-state O-17 NMR. Chemical Communications, 392-393

O-17 magic angle spinning (MAS) NMR has been used to determine the nature of oxygen exchange in ZrW2O8. A highly effective isotopic labelling technique has been developed and 1D NMR and 2D exchange spectroscopy (EXSY) experiments have revealed that m...

Journal Article
Guillarme, S., & Whiting, A. (online). Unexpected temperature, time and solvent effects in the catalytic asymmetric aza-Diels-Alder reaction of an ethyl glyoxylate-derived N-aryl imine with Danishefsky's diene catalysed by a BINOL-zinc complex. Synlett: Accounts and Rapid Communications in Synthetic Organic Chemistry, 711-713

The catalytic asymmetric aza-Diels-Alder reaction of an ethyl glyoxylate-derived N-aryl imine with Danishefsky's diene using a BINOL-zinc complex provides the corresponding cycloadduct with moderate to high enantioselectivity, depending on the solven...

Synthesis, structure and optical characterisation of silicon phthalocyanine bis-esters
Journal Article
Farren, C., FitzGerald, S., Bryce, M., Beeby, A., & Batsanov, A. (online). Synthesis, structure and optical characterisation of silicon phthalocyanine bis-esters. Journal of the Chemical Society-Perkin Transactions 2, 59-66

A range of axially substituted silicon phthalocyanines has been synthesised using various carboxylates as the ligands. 4-tert-Butylbenzoic acid gives rigid, orthogonal axial substituents, whilst a thiophene-containing bis-acetate was conformationally...

Lewis acid-catalysed aza-Diels-Alder versus Mannich reactions of N-diethyl phosphoryl imino dienophiles with oxygenated dienes and application of a chiral lewis acid
Journal Article
Di Bari, L., Guillarme, S., Hermitage, S., Howard, J., Jay, D., Pescitelli, G., Whiting, A., & Yufit, D. (online). Lewis acid-catalysed aza-Diels-Alder versus Mannich reactions of N-diethyl phosphoryl imino dienophiles with oxygenated dienes and application of a chiral lewis acid. Synlett: Accounts and Rapid Communications in Synthetic Organic Chemistry, 708-710

N-Phosphoryl imines react with oxygenated dienes in the presence of Lewis acids to provide either the formal aza-Diels-Alder adduct, or the acyclic Mannich-type addition product, depending upon the catalyst and work up used, which is in agreement wit...

Anion and cation binding by a pendant arm cyclam and its macrobicyclic derivatives
Journal Article
Channa, A., & Steed, J. (online). Anion and cation binding by a pendant arm cyclam and its macrobicyclic derivatives. Dalton Transactions, 2455-2461

A series of transition-metal complexes of N, N', N'', N'''-tetra(3-hydroxypropyl)cyclam (L-1) are reported. The X-ray structures of the compounds reveal pendant arm coordination of one of the alcohol groups to give square-pyramidal metal centres with...

Chemoselective signalling of selected phospho-anions using lanthanide luminescence
Journal Article
Atkinson, P., Bretonniere, Y., & Parker, D. (online). Chemoselective signalling of selected phospho-anions using lanthanide luminescence. Chemical Communications, 438-439

Selectivity in the binding of phosphorylated tyrosine residues to aqua-lanthanide complexes is signalled by changes in spectral form by luminescence emission and H-1 NMR spectroscopy.

Modular nanometer-scale structuring of gel fibres by sequential self-organization
Journal Article
Applegarth, L., Clark, N., Richardson, A., Parker, A., Radosavljevic-Evans, I., Goeta, A., Howard, J., & Steed, J. (online). Modular nanometer-scale structuring of gel fibres by sequential self-organization. Chemical Communications, 5423-5425

Ag(I) and Cu(II) complexes of a series of simple bis( urea) ligands form soft metallogels. X-ray crystallographic results suggests that the gels' structure is based on hydrogen bonding to counter anions and thus suggests a route to tunable gel rheolo...
