ABSTRACT

The mass spectra of the positive and negative ions of cis- and trans-α,β-difluorocinnamic acids and some of their derivative were studied. Fluorine atoms decrease the stabilities of these molecules with respect to electron impact.The mass spectra of the positive and negative ions of the cis and trans isomers differ and can be used to identify the geometrical isomers of α,β-difluorocinnamic acids.Rearrangement processes prevail over processes involving simple bond cleavage under resonance electron-capture conditions. The mass spectra of the positive and negative ions of cis- and trans-α,β-difluorocinnamic acids and some of their derivative were studied.
