Palladium-catalyzed activation of carbon–sulfur bonds allows aryne insertion into arylthiocyanates to generate new C–SAr and C–CN bonds in one step. The readily available starting materials make this method efficient in generating a variety of 1,2-thiobenzonitriles. By choosing an oxygen atmosphere the yields are increased and side reactions are minimized.

A Cu-catalyzed synthesis of 1,2-thiobenzonitriles via oxidative C–N cleavage of 3-aminoindazoles followed by radical coupling with thiols is developed. A diverse array of 1,2-thiobenzonitriles were obtained in good yields with wide substrate scope. Notably, this is the first example of denitrogenative radical coupling with 3-aminoindazoles.
