The reaction between a new (η4)-trans-1,2-α,β-unsaturated diketone-Fe(CO)3 complex derived from trans-1,2-dibenzoylethylene or the corresponding (η2)-Fe(CO)4 complex with MeLi under a CO atmosphere leads to the formation of an (η4)-α-pyrone-Fe(CO)3 complex 3 via the respective (η4)-ketene-Fe (O) complex. The structure of the complex was determined by mass spectrometry, IR, 1H and 13C NMR spectroscopies and was confirmed by X-ray diffraction studies.
