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 ...

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.

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 ...

Organometallic compounds tend to marry metals with aromatic hydrocarbons so that the metal sits above or below the carbon-based group’s flat plane and interacts with the hydrocarbon’s p orbitals. The ...

Scientists have achieved the first real-time visualization of how 'excited-state aromaticity' emerges within just hundreds of femtoseconds and then triggers a molecule to change from bent to planar ...
