Platinum catalysed 3,4- and 1,4-diboration of alpha,beta-unsaturated carbonyl compounds using bis-pinacolatodiboron
Journal Article
Bell, N., Cox, A., Cameron, N., Evans, J., Marder, T., Duin, M., Elsevier, C., Baucherel, X., Tulloch, A., & Tooze, R. (online). Platinum catalysed 3,4- and 1,4-diboration of alpha,beta-unsaturated carbonyl compounds using bis-pinacolatodiboron. Chemical Communications, 1854-1855

Bis-pinacolatodiboron reacts with alpha,beta-unsaturated carbonyl compounds to give 1,4- and unprecedented 3,4-additions in the presence of a second generation Pt(0) catalyst at ambient temperature.

A space group assignment of ZrP2O7 obtained by P-31 solid state NMR
Journal Article
King, I., Fayon, F., Massiot, D., Harris, R., & Evans, J. (online). A space group assignment of ZrP2O7 obtained by P-31 solid state NMR. Chemical Communications, 1766-1767

2-D, P-31 dipolar recoupling magic angle spinning NMR has been used to determine the true symmetry of the low temperature structure of ZrP2O7 for the first time.

Synthesis and characterisation of a new high pressure polymorph of Cu2WS4
Journal Article
Crossland, C., & Evans, J. (online). Synthesis and characterisation of a new high pressure polymorph of Cu2WS4. Chemical Communications, 2292-2293

In this communication we report the synthesis and structural characterisation of a new body centred polymorph of Cu2WS4 prepared using hydrothermal methods. I-Cu2WS4 crystallises in space group I (4) over bar 2m with cell parameters a = b = 5.44427(8... Read More about Synthesis and characterisation of a new high pressure polymorph of Cu2WS4.

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...
