Photolysis of dicyanodiazomethane in Ar matrices has been studied. Dicyanomethylene appears to be the sole product in dilute matrices, and its UV absorption spectrum and a revised IR spectrum are reported. In O2-doped Ar matrices, dicyanomethylene reacts with O2 to give carbonyl cyanide O-oxide as a very photolabile adduct. Four IR bands and a broad UV absorption at 375 nm are assigned to this species. On further photolysis, the carbonyl oxide rapidly decomposes to give carbonyl cyanide, by O-atom expulsion. A strong product absorption at 585 nm is assigned to a charge-transfer complex involving the expelled oxygen, but the precise nature of this species remains unknown.

Irradiation of matrix-isolated dicyanodiazomethane (4) with 254 nm-light leads to the dicyanocarbene 5, which, upon further photoexcitation, undergoes successive isomerizations until a photoequilibrium between the five C3N2 isomers dicyanocarbene (T-5), cyanoisocyanocarbene (T-6), 3-cyano-2H-azirenylidene (S-7), 3-isocyano-2H-azirenylidene (S-8), and diisocyanocarbene (S-9) is reached.
