Abstract
The o.r.d. and c.d. spectra of 1,1′-binaphthyl in ethanol solution have been determined in the region 208–320 nm. Comparison of the curves with those of substituted 1,1′-binaphthyls of established chirality leads to the conclusion that the dextrorotatory (λ= 589 nm) enantiomer of this, the parent, compound has the S-configuration. This result is in accord with that arrived at by chemical correlation with a substituted 1,1′-binaphthyl in which the configuration was assigned by X-ray crystallographic methods.Keywords
