9. When [Fe(CO)s] is refluxed with cyclopentadiene, compound A is formed, which has the empirical formula C8H6O3Fe, and a complicated 'H nmr spectrum. Compound A readily loses CO to give compound B, which has two 'H nmr resonances, one at negative chemical shift and relative intensity one, and the other at around 5 ppm with relative intensity of five. Subsequent heating of B results in the loss of H₂ and the formation of C. Compound C has a single 'H nmr resonance and the empirical formula C₂H5O₂Fe. Treatment of C with iodine results in D, FeC₂H5O₂I. Treatment of C with potassium metal, followed by CH3Br, yields E. Propose structures for A - E.
