Cyclopentanepentone Explained

Cyclopentanepentone, also known as leuconic acid, is a hypothetical organic compound with formula C₅O₅, the fivefold ketone of cyclopentane. It would be an oxide of carbon (an oxocarbon), indeed a pentamer of carbon monoxide.

As of 2000, the compound had yet to be synthesized in bulk, but there have been reports of trace synthesis.^{[1] [2] [3]}

Cyclopentanepentone can be viewed as the neutral counterpart of the croconate anion .

The compound referred to in the literature and trade as "cyclopentanepentone pentahydrate" (C₅O₅·5H₂O) is probably decahydroxycyclopentane (C₅(OH)₁₀).^{[2] [4]}
