Conformational preferences of dinitrile derivatives of (R,R)-tartaric acid were studied by means of NMR, CD and X-ray diffraction techniques. Where as other derivatives of (R,R)-tartaric acid exist predom i nantly in an extended (T) or bent (G–) conformation, (R,R)-tartarodinitriles show pronounced tendency to ward bent G+ conformation. This is rationalized by the presence of the “gauche effect” in volving maximum number of stabilizing in teractions between the polar groups within the tartarodinitrile molecule.
