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.

Novel Strategy

A novel strategy has been developed for the synthesis of indoline-2,3-diones through a metal-free radical-coupling reaction. Alkyl radicals derived from indolin-2-ones through a radical-transfer reaction combine with the tert-butylhydroperoxy radical readily generated from commercially available tert-butyl hydroperoxide to afford 3-(tert-­butylperoxy)indolin-2-one intermediates that can be further transformed into indoline-2,3-diones under air. This strategy provides a ­simple and efficient route to the construction of a C=O bond without the use of any metal catalyst or base.
