Most organic chemical compounds contain loops of six carbon atoms called benzene rings. The nineteenth-century German chemist August Kekulé claimed to have pictured the ring structure of benzene ...

Benzene is big business. A natural part of crude oil, the chemical is a starting material for plastics, drugs, detergents, and more. Yet because of the molecule’s hardiness, limited chemical ...

Characteristic fluorescence of a heterocatenane associated with fast energy transfer between two rings was observed, and the topological chirality of the all-benzene knot was confirmed by enantiomer ...

Yet, attaching a functional handle specifically at the para position of benzene has been challenging due to multiple reactive sites on the ring. Chemists have developed a novel iridium catalyst ...
