A conformational study of 1-X-2-propanol (X= SH, SMe, SOMe, SO2Me,+ SMe2) and their O- acetyl derivatives (X= SMe, SOMe, SO2Me, and+ SMe2) is reported. From the relative values of the vicinal coupling constants in 1H nmr spectra it has been possible to establish the conformational preference. When a density of opposite charge is supported by heteratoms, polar factors determined a great predominance of that conformation in which ...
