Abstract
- The synthesis of a series of ferrocenylvinylketenes as stable η<superscript>4</superscript>-[Fe(CO)<subscript>3</subscript>] complexes (3a–f) was successfully accomplished through the reaction of η<superscript>2</superscript>-[Fe(CO)<subscript>4</subscript>] complexes under mild carbonylation conditions. The reactivity of 3a–f under thermal conditions afforded the unexpected formation of a novel family of (μ<superscript>2</superscript>,η<superscript>3</superscript>-allyl-η<superscript>5</superscript>-oxapentadienyl)diiron pentacarbonyl complexes 5a–f proposed to be formed by a sequence metathesis-haptotropic rearrangement between the starting η<superscript>4</superscript>-vinylketene iron(0) complex 3 and a η<superscript>4</superscript>-vinylcarbene iron(0) complex trapped in situ after a reversible carbonylation process favored by the thermal conditions. An electron density distribution analysis (EDD) of 5e using high-resolution X-ray diffraction data in combination with the DFT framework was performed to understand the electronic communication between the two iron fragments.
