A research team has discovered an electrochemical method that allows highly selective para-position single-carbon insertion ...

Many organic molecules consist of aromatic benzene rings, ie flat rings made up of six carbon atoms. A simple example is graphene. ... These are anti-aromatic and bent into a tub-shape.

While aromaticity makes hexagonal systems like benzene exceptionally stable, ‘anti’-aromaticity makes four-membered rings like cyclobutadiene show opposite tendencies—the delocalized electrons try to ...

This isn’t the first time chemists have wedged open benzene’s ring, Aldridge says. One well-known instance, the Buchner ring expansion, dates to the 19th century.

A team of scientists in Japan have come up with a simple method to synthesise difficult-to-access twisted phenanthrene molecules. Phenanthrene is a planar polycyclic aromatic hydrocarbon, consisting ...

Metal-catalyzed C-H borylation of aromatic rings is considered an efficient way to introduce functional groups to make functional molecules via a boryl moiety. Nonetheless, introducing a boryl group ...

By connecting aromatic rings, their technique forms biaryls, important components of pharmaceuticals; organic electronic materials, such as OLEDs and solar cells; and dyes and pigments.

Chichibabin's hydrocarbon has a sextet of aromatic rings that thermodynamically stabilize radical centers. However, it also has a strong chemical affinity for oxygen atoms and tends to polymerize ...

Homogentisic acid and hydroquinone are both aromatic compounds (the author alludes to this by referring to the benzene ring of hydroquinone) that have a 6-membered, ... Benzene rings. Jeffrey K.
