Nonetheless, introducing a boryl group at a specific position on the 6-membered benzene ring has been rather challenging due to the presence of several reactive sites.

Controlling the positions at which chemical groups attach to benzene rings is vital for the synthesis of materials and medicines. A reaction that targets a normally inaccessible position takes ...

A way to link benzene rings together in a highly ordered three-dimensional helical structure using a straightforward polymerization procedure has been discovered by researchers from RIKEN Center ...

Despite being highly useful, multi-substituted benzene derivatives are rather difficult to synthesize due to the lack of selective methods to install different substituents at the desired positions.

Representation of Benzene Structure. Benzene is often represented in two common ways: Kekulé Structure: This representation shows the alternating single and double bonds within the ring. August ...

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 close look at the mechanism by which benzene starts to polymerize under pressure leads to a new way of understanding and eventually manipulating the synthesis of new carbon-based solids.
