Abstract

We provide the first detailed time-resolved mechanistic information on the protonation of a model of the subsite of [FeFe]-hydrogenase, [Fe₂(µ-pdt)(CO)₄(PMe₃)₂]; the deceptively simple stoichiometric reaction is shown to be limited by the rate of protonation of the basal–apical isomer followed by its rearrangement to the transoid basal form.
