N2 - Di-t-butoxyethyne (1a) reacts with [Fe2(CO)9] affording (tetra-t-butoxycyclopentadienone)-tricarbonyliron(0) (5a), the crystal structure of which has been determined by X-ray diffraction. Treatment of (5a) with trimethylamine oxide affords tetra-t-butoxycyclopentadienone (8), which had been previously converted into hydrocroconic acid (2) and the croconate dianion (3). On the other hand, (5a) with trifluoroacetic acid affords (tetrahydroxycyclopentadienone)tricarbonyliron(0) (5b), which is converted into the croconate dianion (3) by oxidation with molecular oxygen in basic medium.
