Syntheses of 1,2-di- and 1,2,3-trialkyldiaziridines
摘要:
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.

A new simple approach to the synthesis of 1,2-di-and 1,2,3-trialkyldiaziridines has been developed based on direct chlorination of a mixture of the corresponding aldehyde and an excess of primary aliphatic amine in water. The mechanism of this reaction is proposed and confirmed by quantum chemical calculations at the density functional theory level.

spectrometry. The rate constants of particular steps of the reaction were estimated starting from the possibility of formation of the precursor of 1,2-dialkyldiaziridine, N-halogenaminal, due to the amination of the intermediate iminium cation along with the parallel halogenation of the intermediate gem-diamine. The quantum chemical calculations (DFT, B3LYP, 6–31++G(d,p) and 3–21G basis sets) were performed

In the synthesis of diaziridines from amines, carbonyl compounds, and NaOCl in water, the yields of 1,2-dialkyldiaziridines and of 1,2,3-trisubstituted diaziridines prepared from amines with electron-withdrawing substituents in the side chain are less sensitive to changes in pH than the yields of 1,2,3-trialkyldiaziridines with simple alkyl substituents.
