Cyclopentanepentone
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. Related compounds Cyclopentanepentone can be viewed as the neutral counterpart of the croconate anion An ion () is an atom or molecule with a net electrical charge. The charge of an electron is considered to be negative by convention and this charge is equal and opposite to the charge of a proton, which is considered to be positive by conven ... .

Decahydroxycyclopentane
Decahydroxycyclopentane is an organic compound with formula or . It is a fivefold geminal diol on a cyclopentane backbone. The compound can be regarded as the fivefold hydrate of cyclopentanepentone. Indeed, the product referred to in the literature and trade as "cyclopentanepentone pentahydrate" () is now believed to be the decahydroxycyclopentane. The compound was synthesized by Heinrich Will in 1861, although for a long time it was believed to be a hydrate of . It can be prepared by oxidation of croconic acid with nitric acid Nitric acid is an inorganic compound with the formula . It is a highly corrosive mineral acid. The compound is colorless, but samples tend to acquire a yellow cast over time due to decomposition into nitrogen oxide, oxides of nitrogen. Most com .... It can be isolated as water-soluble colorless crystals that melt with dehydration at about 115 °C, and slowly decompose at about 160 °C. See also * Dodecahydroxycyclohexane References ...
