The electrochemicaldemetallation of (η-tetra-t-butoxycyclopentadienone)(ηcyclopentadieny)cobalt, readily available fromdi-t-butoxyethyne leads to tetra-t-butoxyclopentadienone which can be converted into hydrocroconicacid by trifluoroacetic acid hydrolysis and then croconicacid by oxidation in basic medium.
