The effect of pH on the racemisation rate of 4,4′-biquinolyl
The rate of racemisation of optically active 4,4′-biquinolyl varies only slightly from one solvent to another but drops about tenfold in strong acid. The effect is attributed mainly to alteration of the molecular dimensions on protonation.
