Ligand rearrangements in dinuclear iron carbonyl complexes. A novel delocalized bridging vinylcarbene complex

Article abstract of DOI:10.1021/om00151a036

Reaction of [Li] [(μ-CO)(μ-RS)Fe₂(CO)₆] salts with ethoxyacetylene followed by reaction of the anionic intermediate with an electrophile yields bridging vinylcarbene or bridging α,β-unsaturated acyl products resulting from unusual intramolecular rearrangement chemistry involving vinyl and carbonyl ligands.
