The Thermolysis of Dicarbonylcyclopentadienyliron Dimer: The Formation of Biferrocene
Applied Organometallic Chemistry
The thermolysis of dicarbonylcyclopentadienyliron dimer in a sealed tube at 300°C has been reported to produce ferrocene, carbon monoxide, carbon dioxide, cyclopentadiene and elemental iron. We observe in addition to these products the production of biferrocene and elemental carbon. Thermolysis of carbonylcyclopentadienyliron tetramer (produced from the dimer by thermolysis in refluxing xylene) produces ferrocene, iron and carbon monoxide; no biferrocene, carbon dioxide or elemental carbon are produced. A scheme is proposed to account for these products.
