Preparation and Ring-Opening Reactions of N-Diphenylphosphinyl Vinyl Aziridines

Abstract
N-Diphenylphosphinyl-3-ethenyl-2-phenylaziridine (1) and N-diphenylphosphinyl-3-ethenyl-2-(4-bromophenyl)aziridine (2) are prepared by reaction of α-bromo allyllithium with N-diphenylphosphinyl aldimines in the presence of zinc chloride. (1) and (2) undergo efficient SN2’ ring-opening reaction with several nucleophiles.
