A self-consistent model for the conformational analysis of 1,1,2-trisubstituted ethanes is developed, based on the temperature dependence of vicinal proton-proton coupling constants.Synthesis of racemates of 2(R), 3(S)- and 2(S), 3(R)-2,3-dideutero-2-methyl-3-phenyl-1-propanols is accomplished using known reactions of well-defined stereochemistry.By comparing the PMR spectra of undeuterated and deuterated compounds, an unequivocal assignment of benzylic protons is made.Concentration and variable-temperature studies have revealed the existence of very weak intramolecular interaction in three alcohols, p-R-C6H4-CH2-CHMe-CH2-OH, where R = NO2, H and OMe.
