Shock-Wave Study of the High-Temperature UV Absorption and the Recombination of CF3 Radicals

, p. 1681 - 1686 (1980)
The high-temperature UV absorption and the recombination of CF3 radicals have been investigated in shock-wave experiments.CF3 radicals were produced near 1300 K in the fast dissociation of (CF3)2N2 and of CF3NO.At pressure of the bath gas Ar between 0.3 and 25 atm, the recombination was found to be in the unimolecular falloff range closer to the high than to the low pressure limit.Extrapolation to the high pressure limit gives krec,infinite(CF3)=(1.9+/-0.9)E13 cm3 mol-1 s-1 at T=1300 K.Earlier low-temperature results are compared with the present data by using unimolecular rate theory.

On the reaction of perfluoro-aza-propene with oxygen difluoride and fluorination of bis(trifluoromethyl)-hydroxylamine

, p. 145 - 149 (1999)
The reactions of perfluoro-aza-propene CF3NCF2 with an excess of oxygen difluoride OF2 and the fluorination of bis(trifluoromethyl)-hydroxylamine (CF3)2NOH are discussed. Additionally, we present density functional calculations (B3LYP/6-31G*) on bis(trifluoromethyl)-hypofluorite (CF3)2NOF, which clearly show that this molecule is a model substance for the discussion of negative hyperconjugation.

Perfluoronitrosomethane, CF3NO, may be isolated in ca. 50percent yield of a reaction mixture of i-C3H7ONO2 with ZnBr(CF3)*2CH3CN in the presence of aluminium trichloride.Approximately quantitative yields of CnF(2n+1)NO (n = 1, 2, 3, 6) may be obtained by reacting NOCl with Cd(CnF(2n+1))2*glyme.The preparations are described. - Keywords: Perfluoronitrosoalkanes; Syntheses; F-Alkylcadmium complexes

Reactivity of Negative Ions with Trifluoromethyl Halides
Morris, Robert A.,Viggiano, A. A.,Miller, Thomas M.,Seeley, John V.,Arnold, Susan T.,et al.
, p. 10641 - 10645 (2007/10/03)
The kinetics of the reactions of selected anions (A(-)) with the trifluoromethyl halides CF3X (X = F, Cl, Br, I) in the gas phase were measured at 300 K.Reaction rate constants and product branching fractions were determined using a selected ion flow tube (SIFT) instrument.The chosen anions were C5F5N(-), o-, m-, and p-CF3C6H4CN(-), C6F5Br(-), C6F5Cl(-), C6F5CF3(-), C6F5COCH3(-), Fe(-), FeCO(-), SF6(-), SO(-), SO2(-), NO(-), NO2(-), and NO3(-).The reactivity of these systems varies from unreactive to collisional, and a variety of reaction types was found.The results of our present and previous measurements on A(-) + CF3X reactions show that, in cases where nondissociative electron transfer (NDET) is energetically allowed, the total reactivity tends to be high, approaching collisional.This suggests that reactivity in these cases is initiated and controlled by electron transfer from the anion.In addition, association reactions tend to be preempted when NDET is energetically allowed.A few exceptions to these tendencies were found and are discussed.
