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.
Notes:
Es wird über die Gasphasenstruktur von CF3NCl2 berichtet. Der N—C-Bindungsabstand (ra-Wert, Fehlergrenze 3σ-Wert) beträgt 1,470(6) Å, der N—Cl-Abstand 1,733(3) Å und die Bindungswinkel am Stickstoff ClNCl = 111,5(4)° und ClNC = 107,6(5)°.Durch Fluorierung des Amins mit XeF+MF6- (M = As, Sb) können die bis -50°C stabilen Fluorammoniumsalze CF3NCl2F+MF6- synthetisiert werden. Mit dem gleichen Edukt CF3NCl2 reagiert XeF+SbF6- bei -40°C unter ClF-Abspaltung zu CF2 = NClF+SbF6-.
