R. Minkwitz et al., ON THE PREPARATION, SPECTROSCOPIC CHARACTERIZATION AND CRYSTAL-STRUCTURE OF TRIFLUOROMETHYLAZOSULFON-N,N-DIMETHYLAMID (CH3)(2)NS(O)(2)NNCF3, Zeitschrift fur Naturforschung. B, A journal of chemical sciences, 51(4), 1996, pp. 557-562
The reaction of Trifluoronitrosomethan with (CH3)(2)NS(O)(2)NH2 in THF
and Na2CO3 as base give the yellow liquid (CH3)(2)NS(O)(2)NNCF3. The
new compound melts at 283 K and were characterized by vibrational, NMR
and mass spectra. In addition, the crystal structure of (CH3)(2)NS(O)
(2)NNCF3 has been determinated. The azo-compound crystallizes in the o
rthorhombic space group Pnma with a = 1196.7(8), b = 876.9(6), c = 781
.5(6) pm, beta = 90 degrees and four formula units per unit cell.
