The 1H NMR spectra of p-substituted phenyl 2-chloro-2-fluoroethyl sulphides

The 60 MHz ¹H NMR spectra of p-substituted phenyl 2-chloro-2-fluoroethyl sulphides have shown characteristic patterns; in the ABC portion of an ABCX spin system (X = ¹⁹F) of the compounds, one of the subspectra shows an ABC pattern and the other apparently an AB₂ pattern. These spectral patterns have been analysed and the ¹H NMR data obtained are discussed briefly.
