Protonation of a subsite analogue of [FeFe]-hydrogenase: mechanism of a deceptively simple reaction revealed by time-resolved IR spectroscopy.

Joseph A Wright1, Christopher J Pickett.   

Abstract

We provide the first detailed time-resolved mechanistic information on the protonation of a model of the subsite of [FeFe]-hydrogenase, [Fe2(mu-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.
