Aziridines. V. Etude par rmn de l'inversion de l'azote dans les aziridines symétriques à fonetion amine secondaire

This article describes the nitrogen inversion in two symétrie secondary aziridines. It was possible, by nmr, in avoiding the exchange of NH proton with water, to record spectra at different temperatures and to determine the temperature of coalescence. Persistance of coupling HCNH after coalescence demonstrates the attribution of signals multiplicity to both invertomers.
