Regioselective Radical Arene Amination for the Concise Synthesis of ortho-Phenylenediamines
The formation of arene C–N bonds directly from C–H bonds is of great importance and there has been rapid recent development of methods for achieving this through radical mechanisms, often involving reactive N-centered radicals.
