Outline of Final Research Achievements

Diene-iron complexes have been mainly exploited as a protecting group. While the reaction at a carbon adjacent to the diene of the complexes has been the subject of many reports, much less is known reganding the reaction at the diene.
In this study, a novel and unprecedented formation of (vinylketene)iron complexes from (diene)iron complexes has been developed. Treatment of (diene)iron complexes with a Lewis acid such as gallium chloride or aluminum chloride in the presence of aromatic compounds under a CO atmosphere affords (vinylketene)iron complexes via electrophilic aromatic substitution.
These (vinylketene)iron complexes were easily converted to poly-substituted phenols after the treatment with alkyl-substituted alkynes.
