For a number of 1-substituted aziridines and also some 1,2-disubstituted aziridines it has been shown that electron-donating substituents on the nitrogen atom produce a downfield shift of the 15N resonance.The 15N chemical shifts of aziridines correlate with the 15N shifts in N,N-dimethylamines and primary amines as well as with the 17O shifts in oxiranes.A correlation is also observed between the 15N chemical shifts and the electronegativity of the substituents on the nitrogen atom.
