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