Syntheses of 1,2-di- and 1,2,3-trialkyldiaziridines

The reactions of 1,3,5-trialkylhexahydro-1,3,5-triazines with N-chloroalkylamines resulted in 1,2-dialkyldiaziridines, whereas the reactions of N-chloroalkylamines or N,N-dichloroalkylamines with an excess of primary aliphatic amines gave 1,2,3-trialkyldiaziridines.
