Notes:
The stereochemistry of 1,2-disubstituted fluoroethylenes, of general formula RSH2CH=CFR′, has been ascertained from the different magnitudes of the upfield shift effect promoted by fluorine on the 13C NMR absorptions of the underlined γ-carbon of the fluorinated analogue in comparison with those of the protonated parent compounds. Likewise, this assignment was also possible from the study of the values of the 2J(CF) and 3J(CF) coupling constants in the two isomers.
