Cuneane (C8H8, Pentacyclo[3.3.0.0 2,4.03,7.06,8]octane) is a saturated hydrocarbon.[1] Its name is derived from the Latin “cuneus”, meaning a wedge.[2] Cuneane may be produced from cubane by metal-ion-catalyzed σ-bond rearrangement.[3][4] Similar reactions are known for homocubane (C9H10) and bishomocubane (C10H10).[5][6]
The cuneane molecule has three groups of equivalent carbon atoms (A, B, C), which have been also confirmed by NMR.[7] The molecular graph of carbon skeleton of cuneane is regular graph with non-equivalent groups of vertices, and so it is very important test object for different algorithms of mathematical chemistry.[8][9]
Some cuneane derivatives have liquid crystal properties.[10]
