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 ...
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 ...
Chemists have synthesized so-called heteroatom-substituted cage-like 3D molecules. The innovative structures are created by precisely inserting a triatomic unit into the strained ring of a reaction ...
