Macrocyclic Structure

An extremely long-lived localised singlet diradical with π-single bonding character is found in a macrocyclic structure that retards the radical–radical coupling reaction by the “stretch and solvent-dynamic effects”.

Radical Coupling Reaction

The first example of denitrogenative radical coupling with 3-aminoindazoles is presented. A diverse array of 1,2-thiobenzonitriles were obtained in good yields with wide substrate scope via oxidative C–N cleavage of 3-aminoindazoles.

Radical Coupling Reaction

The amphiphilic triblock copolymers PAA-b-PS-b-PAA and PS-b-PAA-b-PS were synthesized by a combination of an atom transfer radical polymerization mechanism and a nitroxide radical coupling reaction or copper-catalyzed azide/alkyne click chemistry.
