Tetrazolo[1,5-a]pyrazine/2-azidopyrazine 9T/9A undergo photolysis in Ar matrix at cryogenic temperatures to yield 1,3,5-triazacyclohepta-1,2,4,6-tetraene 21 as the first observable intermediate, and 1-cyanoimidazole 11 and (2-isocyanovinyl)carbodiimide 22

Methoxy isothiocyanate has been identified as a product of pyrolysis of the silver salt of N-methoxydithiocarbamic acid. It is also formed on FVT of 1-(N-methoxythiocarbamoyl)imidazole and 1-(N-methoxythiocarbamoyl)-1,2,4-triazole. Methoxy isothiocyanate was identified by IR spectroscopy in argon matrices at 10 K supported by good agreement with the ab initio and DFT calculated spectrum. Isopropoxy isothiocyanate was generated from the corresponding silver salt in a similar manner. The oligomerization of MeONCS to trithiolanes and tetrathianes is also described.

1-Cyanoimidazole, 1-cyano-2-methylimidazole, 1-cyanobenzimidazole, and 1-cyano-1,2,4-triazole were prepared by reaction of corresponding azoles with cyanogen bromide.Reactions of cyanogen bromide with sodium benzotriazolide and sodium pyridin-2-olate yield 1-cyanobenzotriazole and 2-cyanatopyridine.
