Novel ruthenium complexes bearing bipyridine-based and N-heterocyclic carbene-supported pyridine (NCN) ligands: the influence of ligands on catalytic transfer hydrogenation of ketones (2021)
Journal Article
Piyasaengthong, A., Williams, L. J., Yufit, D. S., & Walton, J. W. (2022). Novel ruthenium complexes bearing bipyridine-based and N-heterocyclic carbene-supported pyridine (NCN) ligands: the influence of ligands on catalytic transfer hydrogenation of ketones. Dalton Transactions, 51(1), 340-351. https://doi.org/10.1039/d1dt03240b

Transfer hydrogenation (TH) is a powerful synthetic tool in the production of secondary alcohols from ketones by using a non-H2 hydrogen source along with metal catalysts. Among homogeneous catalysts, Ru(II) complexes are the most efficient catalysts...

Comparative analysis of lanthanide excited state quenching by electronic energy and electron transfer processes (2021)
Journal Article
Parker, D., Fradgley, J. D., Delbianco, M., Starck, M., Walton, J., & Zwier, J. M. (2022). Comparative analysis of lanthanide excited state quenching by electronic energy and electron transfer processes. Faraday Discussions, 234, 159 - 174. https://doi.org/10.1039/d1fd00059d

The relative sensitivities of structurally related Eu(III) complexes to quenching by electron and energy transfer processes have been compared. In two sets of 9-coordinate complexes based on 1,4,7-triazacyclononane, the Eu emission lifetime decreased...
