N.m.r. and i.r. spectra are reported for 19 imines of the type PC[graphic omitted]N–C[graphic omitted]QR (P = alkyl or aryl and Q, R =(H,alk), (alk,alk), or –[CH2]n–). The variation in |Jab| with structure is examined, and evidence is found for conformational effects similar to those for allylic coupling. The CN stretching frequencies fall into characteristic and separate ranges for P = alkyl and P

2-Alkyl-3-aryl- or -heteroaryloxaziridines are prepared in a particularly advantageous manner by oxidizing corresponding N-alkyl-aryl- or -heteroarylaldimines with an aromatic percarboxylic acid or a salt thereof in the presence of water, a water-soluble base, and a water-miscible solvent, at temperatures below 30° C. Using this method, it is also possible to obtain novel 2-alkyl-3-aryloxaziridines.
