A team of researchers affiliated with several institutions in Japan has developed a way to create catenanes and a molecular trefoil knot out of para-connected benzene rings. In their paper published ...

Chemical syntheses in liquids and gases take place in three-dimensional space. Random collisions between molecules have to result in something new in an extremely short time. But there is another way: ...

Aryl halides*1) with a benzene ring directly bonded to a halogen atom are readily available and chemically stable, so they are used as a source of benzene rings in organic synthesis. For example, a ...

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 pathways ...

The unspoken promise of new technologies is that they will advance and enhance our picture of the world — that goes double for the ones that are specifically designed to let us look closer at the ...

A huge molecular wheel has set a new record as the largest aromatic ring (Nat. Chem. 2020, DOI: 10.1038/s41557-019-0398-3). The molecule could be a step toward making even bigger rings that serve as a ...
