The concept of aromaticity underpins much of modern organic chemistry, describing the unusual stability and reactivity of cyclic molecules whose π-electrons are delocalised over a planar framework.

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 ...

Organic chemistry is the study of the structure, properties, composition, reactions, and preparation of carbon-containing compounds. Most organic compounds contain carbon and hydrogen, but they may ...
