Chemistry Molecular mechanics

Researchers from The University of Osaka used electricity to drive a reaction to form a novel hetero[8]circulene consisting of five hexagons and three pentagons (called a dioxaza[8]circulene). The dioxaza[8]circulene is unsymmetrical, unlike existing hetero[8]circulenes. The novel molecule can be produced from commercially available materials by a two-step method that simultaneously forms six new bonds with only water as a byproduct. The dioxaza[8]circulene may have potential as a photocatalyst, and be used to speed up reactions triggered by light.
