Rearrangement processes in gas-phase negative ions. 1. Difluorocinnamic acid and some other organofluorine compounds

Rearrangement processes with the successive splitting out of HF and CO₂ molecules, the contribution of which to the scheme of the fragmentation of the negative molecular ions reaches 99%, are realized in the resonance capture of thermal electrons by molecules of organofluorine compounds (derivatives of di- and tetrafluorocinnamic acids and 1,4-diaryltetrafluorobutadiene).Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 7, pp. 1547–1549, July, 1990.
