| Abstract: | Gas Phase Structure of CF3NCl2 and Preparation of CF3NCl2F+MF6? (M = As, Sb) and CF2 = NCl2F+SbF6? The gas phase structure of CF3NCl2 is reported. The following skeletal parameters are derived (ra-values, error limits are 3σ values): N? C = 1.470(6) Å, N? Cl = 1.733(3) Å, ClNCl = 111.5(4)° and ClNC = 107.6(5)°. CF3NCl2F+MF6? is prepared by fluorination of CF3NCl2 with XeF+MF6?. The same educt CF3NCl2 reacts with XeF+SbF6? at ?40°C to CF2 = NClF+SbF6? under elimination of ClF. |
