The Newcastle University research output collection, currently available on ePrints, will shortly be moving to a new open repository platform, Figshare. To prepare for the data migration we have paused adding new content to ePrints, and will resume once the new repository is launched. During this time you will continue to have access to ePrints (but no new content will appear). We will share updates here when available.

Abstract

Rates of proton transfers between lutH(+) (lut = 2,6-dimethyl-pyridine) and [Ni(XPh)(PhP{CH2CH2PPh2}(2))](+) (X = O, S or Se) are slow and show little variation (k(O) :k(S) :k(Se) = 1:12:9). This unusual behaviour is a consequence of sterics affecting the optimal interaction between the reactants prior to proton transfer.
