Sulfonylative and azidosulfonylative cyclizations by visible-light-photosensitization of sulfonyl azides in THF (2017)
Journal Article

The generation of sulfonyl radicals from sulfonyl azides using visible light and a photoactive iridium complex in THF is described. This process was used to promote sulfonylative and azidosulfonylative cyclizations of enynes to give several classes o...

The contrasting effects of diethylmethylamine during reduction of protons and oxidation of formic acid in diethylmethylammonium-based protic ionic liquids (2017)
Journal Article
Goodwin, S., Muhammad, S., Tuan, L.-P., & Walsh, D. (2018). The contrasting effects of diethylmethylamine during reduction of protons and oxidation of formic acid in diethylmethylammonium-based protic ionic liquids. Journal of Electroanalytical Chemistry, 819, https://doi.org/10.1016/j.jelechem.2017.10.021

Ionic liquids are formally defined as liquids that consist entirely of ions, and which are liquid below 100 C. As these liquids are being proposed for use in a range of electrochemical devices and applications, understanding the electrochemical beha...

Electroanalysis of neutral precursors in protic ionic liquids and synthesis of high-ionicity ionic liquids (2017)
Journal Article
Sean, G., Daniel, S., Joshua, G., Jones, R., & Walsh, D. A. (in press). Electroanalysis of neutral precursors in protic ionic liquids and synthesis of high-ionicity ionic liquids. Langmuir, 33(34), https://doi.org/10.1021/acs.langmuir.7b02294

Protic ionic liquids (PILs) are ionic liquids that are formed by transferring protons from Brønsted acids to Brønsted bases. While they nominally consist entirely of ions, PILs can often behave as though they contain a significant amount of neutral...

Closed bipolar electrodes for spatial separation of H2 and O2 evolution during water electrolysis and the development of high-voltage fuel cells (2017)
Journal Article

Electrolytic water splitting could potentially provide clean H2 for a future ‘Hydrogen Economy.’ However, as H2 and O2 are produced in close proximity to each other in water electrolysers, mixing of the gases can occur during electrolysis, with pote...
