Enantiomeric diaziridines have been partially separated by chromatography on triacetlycellulose. (−)-2, (+)-4, and (−)-4 were obtained almost pure, enantiomeric purities (Table 1) being measured by 1H NMR in the presence of optically active additives. The same procedure was tested for monitoring racemizations (Table 2) which were also studied, with higher accuracy, by polarimetry. The barriers to ...
