On September 11, 1991, Evans, Richard A.; Lorencak, Primoz; Ha, Tae Kyu; Wentrup, Curt published an article.SDS of cas: 5098-14-6 The title of the article was HCN dimers: iminoacetonitrile and N-cyanomethanimine. And the article contained the following:
Iminoacetonitrile H(NC)C:NH (I) has been prepared by two methods: (i) thermal decomposition of the tosylhydrazone salts H2N(NC)C:NN-TosM+ (Tos = tosyl, M = Na, Li) at 200° and (ii) Ar matrix photolysis of azidoacetonitrile. Ab initio calculations indicate that Z-I is of slightly lower energy than E-I, and this is confirmed by the IR spectra with use of the thermal methods. E-I/Z-I undergo photochem. interconversion, giving a ca. 3:1 photostationary E:Z ratio. E-I and Z-I are fully characterized by their gas-phase, matrix, and thin-film IR spectra, which are in excellent agreement with ab initio calculations, by 1H and 13C NMR spectroscopy in solution, and by mass spectrometry. I polymerizes in solution above -40°; pyrolysis produces HCN, and matrix photolysis produces HNC and van der Waals complexes containing HNC. N-tert-Butyliminoacetonitrile thermally fragments to tert-Bu isocyanide and HCN. N-Cyanomethanimine H2C:NCN (II) has also been prepared by two methods: (i) pyrolysis of trimethylenetetrazole (III) at 500-800° and (ii) pyrolysis of ditetrazolopyrazine (IV) at 600-850°. Both methods are extremely clean. II is fully characterized by its IR spectrum in agreement with ab initio calculations and, in conjunction with other work, by its mass and millimeter-wave spectra. II is thermodynamically stable in the gas phase up to ca. 800° at low pressure and short contact times but polymerizes in the solid state above -100°. The experimental process involved the reaction of 2-Aminomalononitrile 4-methylbenzenesulfonate(cas: 5098-14-6).SDS of cas: 5098-14-6
