Action of atomic fluorine on E- and Z-2-butene

Irradiation of N2F4(NF2) with E- and Z-2 butene in the gas phase leads to addition of F and NF2 across the double bond in a non-stexeoselective manner and abstraction of H to give 2- butenyl radicals which interconvert rapidly before being trapped by NF2 to yield E- and Z-1- difluoroamino-2-butene and 3-difluoramino-1-butene. The configurational instability of the 2- butenyl radicals is attributed to the exothermicity of F atom abstraction. These results are contrasted with those of other workers who observed that in condensed phase reactions abstraction by t-butoxy radical leads to 2-butenyl radicals which are configurationally stable.

The elementary deactivation processes of CHF(, v'2) by H2(X1Σg+), O2(X3Σg-, and CO(X1Σ+) were studied in a quasistatic photolysis chamber.Determination of time and spectrally resolved laser-induced fluorescence of CHF (1A'', v'2) in single vibronic excited levels (SVL) (0 2 1A' (0,0,0)> was generated in the fluorescence cell by multiphoton dissociation (MPD) of CH2F2.The overall CHF(, v'2)-depletion rate constants: .Asignificant increase of the rate constants for higher vibronic states was observed.The contribution of vibration deactivation to the overall depletion of the initially excited state was found to be small (2 = 1 and Δv'2 = 2 respectively.The reaction mechanisms are discussed. - Keywords: Elementary Reactions / Energy Transfer / Photochemistry
