Investigations on doubly nitrogen-15 labeled isocyanogen (CNCN)

The doubly nitrogen-15 labeled isotopomer C15NC15N of isocyanogen (CNCN) has been prepared by a known route in three steps from [15N2]hydrazine sulfate and quadricyclanone. The chemical reactivity of C15NC15N has been explored. Most of the typical isonitrile reactions are too slow to compete with the polymerization of isocyanogen which starts as low as -80°C; defined products were only obtained on bromination to Br2CNCN (7) and on FVT at 750°C to give partial conversion to cyanogen (NCCN). The 15N and 13C NMR spectra of 1, 4, C15NC15N, 15NCC15N, and [15N2]7 are discussed; important aspects are the previously "missing" cyano group in CNCN which has now been identified and an unusually large 13C-15N coupling (1J = 48.9 Hz) in the central bond of isocyanogen.
