Aromaticity rules
In 1931, Erich Hückel published a landmark paper — the seed of the now famous 4n + 2 rule for aromaticity in annulenes that bears his name. Electron counting has since been extended to other classes of compounds, resulting in a multitude of rules aiming to capture the concept of aromaticity and its impact in chemistry.

A crystalline monosubstituted carbene
So far, monosubstituted carbenes have only been spectroscopically characterized at very low temperatures. Now, it has been shown that a bulky, chemically inert, amino substituent is enough to tame the intrinsic tendency of carbenes towards dimerization, enabling their isolation at room temperature.
