Conjugation of aziridine and benzene rings in a number of p-substituted N-phenylethyleneimines

Abstract

p-Methyl- and p-halo-substituted N-phenylethyleneimines were synthesized, and their structures were confirmed by their IR, UV, and PMR spectra. It was concluded that the introduction of the indicated substituents into the para position relative to the aziridine ring increases conjugation of the benzene and aziridine rings as compared with unsubstituted N-phenylethyleneimine.
