That even cationic fragments of late transition metals can activate OH bonds in the gas phase is shown by studies of reaction (a) (RH, CH 3 ), in which a large deuterium isotope effect can be observed ( k H / /k D > 15). An oxidative addition mechanism is proposed for this transformation; the first step is the coordination of the dipolar H 2 O or CH 3 OH molecule to the [FeCH 3 ] + fragment, while the rate‐determining step is the transfer of the H atom of the ROH group to the Fe atom.
