Aromatic compounds play an important role in chemistry and biology as well as in numerous branches of industry. Although aromaticity was initially thought to be exclusive to carbon cycles, it has ...

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 ...

Circularly conjugated compounds with 4n+2 pi-electrons are known as aromatic compounds. They are generally stable and are therefore found in our surroundings. On the other hand, anti-aromatic ...
