Benzene is big business. A natural part of crude oil, the chemical is a starting material for plastics, drugs, detergents, and more. Yet because of the molecule’s hardiness, limited chemical pathways ...

It has a very complex structure, but its major building block is the planar ring of six nitrogen atoms, which is called hexazine anion, as it has a negative charge. The arrangement of nitrogen atoms ...

Aryl halides*1) with a benzene ring directly bonded to a halogen atom are readily available and chemically stable, so they are used as a source of benzene rings in organic synthesis. For example, a ...

This illustration visualizes a novel electrochemical transformation in which a single carbon atom—derived from a diazo compound—is selectively inserted into the pyrrole ring via a distonic radical ...

A version of this story appeared in Volume 96, Issue 41 Saito explains that selenium’s large size allows overlapping σ orbitals from the six atoms to create aromaticity. The phenylselenyl groups ...

(Nanowerk News) Scientists at Tokyo Institute of Technology have shown that copper oxide particles on the sub-nanoscale are more powerful catalysts than those on the nanoscale. These subnanoparticles ...
