Irradiation of 4-diazo-4H-imidazole (1) in an argon matrix at 10 K at a wavelength of λ = 313 nm leads to rapid loss of nitrogen and the formation of 4H-imidazol-4-ylidene (2). Upon photoexcitation of 4H-imidazol-4-ylidene (2) at wavelengths longer than 570 nm, the ring-opened carbene S-6 can be detected. S-6 can be photochemically converted (λ > 310 nm) to 2-cyano-2H-azirene (5). In CO-doped argon matrices, 2 is trapped and 4H-imidazol-4-ylidene ketene (7) can be observed. |
