Iron tetracarbonyl complexes of γ-acetoxy-α,β-unsaturated esters react with silyl enol ethers in the presence of boron trifluoride-etherate to give substitution in the γ-position. The results are interpreted as being indicative of the intermediacy of a tetracarbonyliron-allyl cation complex which reacts at the terminus remote from the ester function.
