Dicarbonyl(η5-cyclopentadienyl)-(2,2-dimethylpropylidene)iron(II) and -(2-methyl-2-phenylpropylidene)iron(II) tetrafluoroborates, (6) and (10), prepared by protonation of the analogous Fe(II) α-ethoxyalkyls, rearrange to dicarbonyl(η5-cyclopentadienyl)-(η2-2-methylbut-2-ene)iron(II) and -(η2-2-methyl-1-phenylprop-1-ene)iron(II) tetrafluoroborates, (7) and (11), by shift of a methyl and phenyl group, respectively, from the β to the α carbon atom.
