In the Fe⊕-mediated Meerwein-Ponndorf-Verley-Oppenauer reaction in the gas phase the following is noteworthy: besides the conventional hydride transfer, an analogous methanide migration has been detected for the first time. In contrast, in the case of sterically crowded alkoxides such as 1 a β-CH3 rearrangement takes place.
