A method for the synthesis of 1-[ω-(3,3-dialkyldiaziridin-1-yl)alkyl]-3,3-dialkyldiaziridines based on the reaction of ketoxime O-arenesulfonates with alkylenediamines was developed. Diastrereomers (the racemic and meso forms) of 1-[2-(3,3-dimethyldiaziridin-1-yl)ethyl]-3,3-dimethyldiaziridine were isolated. The structure of the meso form was confirmed by X-ray diffraction analysis.

By means of the dipole moments of several imidic acid esters the conformation at the CO bond and the configuration at the CN bond have been determined. Use was made of the graphical comparison of a phenyl-derivative with the para-substituted analogue [7] in combination with cyclic model compounds having forced stereochemistry. The results obtained are conclusive for the N-alkyl-derivatives which are
