WebbWe report here the synthesis of a novel family of N-CF3 hydrazines from a direct way involving the available and cheap Langlois reagent (CF3SO2Na). These derivatives have shown very high stability whatever the conditions used and are excellent precursors for building previously inaccessible N-CF3 functionali Webb1 feb. 1971 · Their spectrum, which is effectively a photo- electron spectrum of the CF3 radical, shows a long progression of bands each separated by about 830 cm . They assign this as a transition from the pyramidal ground state of CF3 to the planar CF~ ion in which the out-of-plane bending vibration is excited.
WebbThe reflected shock tube technique with multipass absorption spectrometric detection (at a total path length of ∼1.75 m) of OH-radicals at 308 nm has been used to study the dissociation of CF 3 -radicals [CF 3 + Kr → CF 2 + F + Kr (a)] between 1803 and 2204 K at three pressures between ∼230 and 680 Torr.
