Visitation will be held In organic chemistry, allenes are organic compounds in which one carbon atom has double bonds with each of its two adjacent carbon atoms (R2C=C=CR2, where R is H or some organyl group). Allenes are classified as cumulated dienes. The parent compound of this class is propadiene (H2C=C=CH2), which is … See more For many years, allenes were viewed as curiosities but thought to be synthetically useless and difficult to prepare and to work with. Reportedly, the first synthesis of an allene, glutinic acid, was performed in an attempt to prove … See more Use The reactivity of allenes is rich and opens wide possibilities for discovery. The two π-bonds are … See more • Compounds with three or more adjacent carbon–carbon double bonds are called cumulenes. See more • Brummond, Kay M. (editor). Allene chemistry (special thematic issue). Beilstein Journal of Organic Chemistry 7: 394–943. See more Geometry The central carbon atom of allenes forms two sigma bonds and two pi bonds. The central carbon atom is sp-hybridized, and the two terminal … See more Although allenes often require specialized syntheses, the parent allene, propadiene is produced industrially on a large scale as an equilibrium mixture with methylacetylene See more Many rings or ring systems are known by semisystematic names that assume a maximum number of noncumulative bonds.
