Aminyl radicals of the type •NR2, featuring a nitrogen-centered unpaired electron, are highly reactive intermediates that are notoriously difficult to isolate in the condensed phase. Herein, we report the synthesis of thio-, seleno- and telluro-aminyl radicals 2–4, obtained in one step from reactions of an isolable triplet nitrene with diphenyldichalcogenides. Radicals 3 and 4 represent the first stable examples of seleno- and telluro-substituted aminyl radicals. Compounds 2–4 were characterized by single-crystal X-ray diffraction, electron paramagnetic resonance and UV/Vis absorption spectroscopy. This work not only expands the family of isolable nitrogen-centered radicals, but also opens new avenues for main-group radical chemistry involving heavier p-block elements.
