(η1-Acryloyl)tetracarbonylferrates 2a-d reacted with acyl halides 3a-c or ethyl fluorosulfonate in THF at 20°C to give (η3:η1-allylacyl)tricarbonyliron complexes 5a-h in moderate yield. (1-syn-(Benzoyloxy)-3-syn-phenyl-η3:η 1-allylacyl)tricarbonyliron (5a) reacted with nonacarbonyldiiron in diethyl ether at 35°C to give a binuclear α,β-unsaturated alkylidene complex, (η-1-(η1-benzoyloxy)-3-syn-phenyl-η 3:η1-allyl)hexacarbonyldiiron(Fe-Fe) (7) in 72% yield. Thermolysis of 5a in toluene at 105°C for 1 h gave 7 in 78% yield. The formation of 5 or 7 could be explained by assuming the formation of a mononuclear η1-vinylcarbene complex or a η3-vinylcarbene complex as a reaction intermediate, respectively.
