Abstract

The conformational energy of the (η⁵-cyclopentadienyl) iron(II) dicarbonyl group was determined by variable-temperature ¹H NMR spectroscopic studies on cis-4-phenyl-1-(η⁵-cyclopentadienyl) iron(II) dicarbonyl cyclohexane. This is the first determination of the A-value of a group with a transition metal directly attached to a cyclohexane ring. The stereospecific synthesis of cis- and trans-4-phenyl-1-(η⁵-cyclopentadienyl) iron(II) dicarbonyl cyclohexane and cis- and trans-4-tert-butyl-1-(η⁵- cyclopentadienyl) iron(II) dicarbonyl cyclohexane and the X-ray crystal structure of cis-4-tert-butyl-1-(η⁵-cyclopentadienyl) iron(II) dicarbonyl cyclohexane are reported.
