We report the synthesis and full characterization of the first NHC-stabilized triazenyl radicals, obtained by one-electron reduction of the corresponding triazenyl cations with potassium metal. Triazenyl radicals were characterized by single-crystal X-ray diffraction, EPR spectroscopy. These radicals reversibly oxidize back to the cations upon treatment with transition metal sources or electrophiles, and abstract H atom from xanthene to form a new N-H bond at the center nitrogen atom. Potential application of the redox couple between triazenyl cation and triazenyl radical was demonstrated as cathode active materials in lithium ion batteries. This results of this study were published in the Journal of of the American Chemical Society in November, 2017 and also it was introduced in the magazine, C&EN(Chemical & Engineering News), published by the American Chemical Society in November, 2017.
