Cuneane
Encyclopedia
Cuneane is a saturated
hydrocarbon
. Its name is derived from the Latin “cuneus”, meaning a wedge. Cuneane may be produced from cubane
by metal-ion-catalyzed σ-bond rearrangement. Similar reactions are known for homocubane (C9H10) and bishomocubane (C10H10).
The cuneane molecule has three groups of equivalent carbon atoms (A, B, C), which have been also confirmed by NMR
. 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
.
Some cuneane derivatives have liquid crystals properties.
Saturation (chemistry)
In chemistry, saturation has six different meanings, all based on reaching a maximum capacity...

Hydrocarbon
In organic chemistry, a hydrocarbon is an organic compound consisting entirely of hydrogen and carbon. Hydrocarbons from which one hydrogen atom has been removed are functional groups, called hydrocarbyls....

Cubane
Cubane is a synthetic hydrocarbon molecule that consists of eight carbon atoms arranged at the corners of a cube, with one hydrogen atom attached to each carbon atom. A solid crystalline substance, cubane is one of the Platonic hydrocarbons. It was first synthesized in 1964 by Philip Eaton, a...

Regular graph
In graph theory, a regular graph is a graph where each vertex has the same number of neighbors; i.e. every vertex has the same degree or valency. A regular directed graph must also satisfy the stronger condition that the indegree and outdegree of each vertex are equal to each other...
