Notizen:
The 1H and 19F NMR spectra of the CH2FCHF group in FCH2CHFCO2C2H5 were analysed on the basis of an ABCXY spin system. The non-equivalence of the methylene protons is discussed in terms of rotational isomerism. It is concluded that the dominant rotamer is probably considerably distorted from a perfectly staggered orientation. The variation of 3JHF with substituent electronegativity is reviewed.
