cubane

It is used as a key step, for instance, in a synthesis of cubane.

The molecule in question, once considered an impossibility, is called cubane.

Cubane and its derivative compounds have many important properties.

I forget how many double bonds cubane has, but I think it is aromatic.

A solid crystalline substance, cubane is one of the Platonic hydrocarbons.

The 90-degree bonding angle of the carbon atoms in cubane means that the bonds are highly strained.

These cubanes are so-called because they have a structure related to CH, cubane.

One such compound is called cubane which is like it sounds a cube of carbons.

Several Platonic hydrocarbons have been synthesised, including cubane and dodecahedrane.

The geometry of the anion cluster is that of an incomplete cubane.

The energy in its strained carbon bonds may or may not account for cubane's apparent ability to attack some cancer cells.

In the case of the molecule cubane, the angles formed at the molecule's corners between adjacent bonds are 90 degrees.

This is especially seen in molecules like cubane (look up the structure) where the idea of steric strain is very clearly visible.

Once formed, cubane is quite kinetically stable, due to a lack of readily available decomposition paths.

Cuneane may be produced from cubane by a metal-ion-catalyzed σ-bond rearrangement.

The next challenge was to substitute other atoms for the eight hydrogen atoms attached to cubane's corners.

Cubane is one of a series of molecules inspired by the Greek philosopher Plato.

Its structure is known in one of the metastable phases of silicon and is similar to cubane.

Philip Eaton's synthesis was difficult and lengthy, and required cubane (rare enough to begin with) as a starting point.

Dr. Eaton and his associates plan to synthesize a family of many peculiar molecules related to cubane.

Many cage-like compounds like adamantane and cubane with high symmetry have very high melting points.

The tetrameric cluster consists of a distorted cubane, with carbon and lithium atoms at alternate corners.

Polycyclic alkanes include cubane, basketane, and housane.

"It wouldn't surprise me to find that the road to bulk synthesis of cubane will also depend on acetylene," Dr. Eaton said.

The Favorskii rearrangement established the carbon skeleton of cubane, and further synthetic manipulations provided the desired unfunctionalized target.
