Cyclopropenone is an organic compound with molecular formula C
3H
2O consisting of a cyclopropene carbon framework with a ketone functional group. It is a colorless, volatile liquid that boils near room temperature.[1] Neat cyclopropenone polymerizes upon standing at room temperature.[2] The chemical properties of the compound are dominated by the strong polarization of the carbonyl group, which gives a partial positive charge with aromatic stabilization on the ring and a partial negative charge on oxygen. It is an aromatic compound.[3][4]
