Synthesis of cyclocarbon According to these IBM researchers, the synthesized cyclocarbon has alternating triple and single bonds, rather than being made of entirely of double bonds. This supposedly makes this molecule a semiconductor .
The molecule is a ring of eighteen carbon atoms, connected by alternating triple and single bonds; thus, it is a polyyne and a cyclocarbon. Cyclo[18]carbon is the smallest cyclo[ n ]carbon predicted to be relatively stable, with a computed strain energy of 72 kilocalories per mole.
Norbornane (also called bicyclo[2.2.1]heptane). Unsubstituted cycloalkanes that contain a single ring in their molecular structure are typically named by adding the prefix "cyclo" to the name of the corresponding linear alkane with the same number of carbon atoms in its chain as the cycloalkane has in its ring.
Depending on the synthesis method, carbide precursor, and reaction parameters, multiple carbon allotropes can be achieved, including endohedral particles composed of predominantly amorphous carbon, carbon nanotubes, epitaxial graphene, nanocrystalline diamond, onion-like carbon, and graphitic ribbons, barrels, and horns.
Harry Laurence Anderson FRS is a British chemist in the Department of Chemistry, University of Oxford.He is well known for his contributions in the syntheses of supramolecular systems (porphyrin nanorings and nanowires), exploration of the extraordinary physical properties of large pi-conjugated systems, and synthesis of cyclo[18]carbon.

A cyclic compound (or ring compound) is a term for a compound in the field of chemistry in which one or more series of atoms in the compound is connected to form a ring. ...
The synthesis of epoxides via this method serves as an important retrosynthetic alternative to the traditional epoxidation reactions of olefins. Johnson–Corey–Chaykovsky Reaction. The reaction is most often employed for epoxidation via methylene transfer, and to this end has been used in several notable total syntheses (See Synthesis of ...
