Chlorodifluoromethyl(trifluoromethyl)diselenane, CF 3 SeSeCF 2 Cl, has been prepared by the reaction of CF 3 SeCl with Se=CF 2 . CF 3 SeSeCH 3 has been synthesized via a new route from CF 3 SeSeCF 3 and CH 3 SeSeCH 3 . CF 3 SeSeCF 2 Cl is unstable with respect to the symmetric diselenanes CF 3 SeSeCF 3 and CF 2 ClSeSeCF 2 Cl. The new compound CF 3 SeSeCF 2 Cl has been characterized by 77 Se, 19 F, and 13 C NMR, IR, and mass spectra. Additional data from the 77 Se, 19 F, 13 C, and 1 H NMR spectra are reported for the known compounds CF 3 SeSeCH 3 and CF 2 ClSeSeCF 2 Cl. |
