Photolysis of 2,3-diazidonaphthalene-1,4-dione (1) in methyltetrahydrofuran matrices forms 2-(λ1-azaneyl)-3-azidonaphthalene-1,4-dione (vinylnitrene 3 2), as confirmed by electron paramagnetic resonance spectroscopy. The zero-field splitting (zfs) parameters for 3 2 (D/hc = 0.5338 cm–1, and E/hc = 0...
