The term aromaticity is a basic, long-standing concept in chemistry that is well established for ring-shaped carbon compounds. Aromatic rings consisting solely of metal atoms were, however, heretofore ...

After nearly 50 years of failed attempts and scientific speculation, chemists at Saarland University have achieved what many ...

A long-standing chemistry challenge has been solved with the synthesis of a five-atom silicon aromatic ring. The breakthrough validates decades of theory and points toward new industrially relevant ...

Image generated from an X-ray crystal structure shows a molecule with a five-membered silicon ring at its core. This X-ray crystal structure of the pentasilacyclopentadienide synthesized by David ...

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 ...
