The littlest aromate
In recent months, two research groups have reported new molecules containing three-membered aromatic boron rings. The chemists behind each of these discoveries made a claim that their molecules have established a new precedent as the smallest or lightest aromatic species now known. Both have a legitimate shot at being named a record holder, but their cases hinge on how chemists define aromaticity.
For the claim of lightest aromatic ring, a team led by . . .
