Replacing a carbon atom in an aromatic ring with a nitrogen atom is one of those exercises that’s easy to do on paper with a pencil and eraser but tough to accomplish in a reaction flask.

Especially if that atom is a nitrogen. Chemists at the University of Oklahoma have now unveiled a new strategy for expanding 5-membered aromatic rings that already contain a nitrogen, by slipping ...

For the first time, a compound containing aromatic rings of nitrogen atoms has been synthesized. The compound of nitrogen and potassium was produced under extremely high pressures and temperatures.

These compounds are arranged in a ring and, in this case ... the easier it is to transition it to being used for other nitrogen-containing aromatic compounds, further expressing the practicality ...

Like many other active core scaffolds found in biologically active compounds, the indole motif consists of rings of atoms. Eight carbon atoms and one nitrogen atom are connected to form a skeleton in ...

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 ...
