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.
A research team has discovered an electrochemical method that allows highly selective para-position single-carbon insertion ...
In 1825 Michael Faraday isolated a sweet-smelling chemical that he dubbed bi-carburet of hydrogen. That molecule, better ...
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.
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.
Nevertheless, little is known yet in the emerging field of precise, abiotic through-space control of SEAr reactions. While directing groups installed on the side of aromatic rings have been used ...
