Abstract

The barriers to partial rotation around the central single bond in chiral dienes HOCMe₂-(-CC1=CC1-)-₂R have been determined by coalescence of either 1H NMR signals (X = CH2OCH3) or 13C NMR signals (X = H). In the presence of the optically active shift reagent (+) − Eu(hfbc)3 all 1H signals were split at temperatures where the interconversion of enantiomers is slow. The temperature dependence of ...
