Abstract
Determination of the absolute configuration of 1,1′-binaphthyls by the use of Cotton effects associated with the short wave band of the electronic absorption spectra is discussed and applied to examples with substituents in the 8- and 8′-positions. Racemisation parameters are determined for 1,1′-binaphthyl-8,8′-diacetic acid in 0·1N-aqueous sodium hydroxide solution.Keywords
