Abstract
The reaction between a new (eta(4))-trans-1,2-alpha,beta-unsaturated d iketone-Fe(CO)(3) complex derived from trans-1,2-dibenzoylethylene or the corresponding (eta(2))-Fe(CO)(4) complex with MeLi under a CO atmo sphere leads to the formation of an (eta(4))-alpha-pyrone-Fe(CO)(3) co mplex 3 via the respective (eta(4))-ketene-Fe (O) complex. The structu re of the complex was determined by mass spectrometry, IR, H-1 and C-1 3 NMR spectroscopies and was confirmed by X-ray diffraction studies. ( C) 1997 Elsevier Science S.A.
