Notizen: Summary A racemic mixture of the molecularly dissymmetric compound 1,1′-binaphthyl will spontaneously develop optical activity when melted, cooled, and allowed to crystallize. The distribution of optical rotations in individual samples shows that the resolutions occur in a truly spontaneous manner (i.e., without the influence of any external chiral agent). However, addition of small amounts of certain chiral compounds promotes the generation of one enantiomeric form of binaphthyl. The results are often not completely consistent and this suggests that the nucleation of binaphthyl is sensitive to very low concentrations of unknown chiral agents.
