The title compound (I) has been synthesized for the first time. Their spectra of the pure enantiomer and the racemic mixture (both dissolved in CCl4 to an association allowing concentration) are different from each other in characteristic features. The differences vary on changing the temperature and/or concentration and are discussed in terms of thermodynamic properties of the H bond, linking the molecules by NH[sbnd]OS-bridges. In particular, the free NH bands of the pure enantiomer are about 10% less intensive than those of the racemic mixture under the same conditions, the case of high, association-free dilution excluded. Rather dramatic findings can be reported describing the association between the pure (R)-butan-2-ol and I. Only by change of the configuration of one of the partners differences of about one order of magnitude in the equilibrium constants are obtained. |
