The synthesis of nitrogen heterocycles such as 1 and 2 from cyanogen and oxalyl halides is possible in one step and in yields of 60–70% with the catalyst system NR 4 ⊕ X ⊖ /HX, X = Cl, Br. Compound 1 can be easily cleaved to give functionalized imidazoles, and 2 is of interest owing to its bactericidal activity as well as its possible use as a synthetic building block.
