Abstract
The crystallization of 1, l'—binaphthyl from its racemic melt is an example of spontaneous generation of optical activity. The distribution of specific rotations in 200 individual samples varied from [α]D = —218 degrees to [α]D = +206 degrees with a mean of +0.14 degree and standard deviation of 86.4 degrees. This resolution into enantiomers is determined by chance development, with equal probability, of right- or left-handed crystallites; it can be controlled and made stereospecific by addition of dissymmetric compounds at low concentrations.Keywords
