Carbon tetrahalide reacts rapidly with 2-phenylsulfonyl aziridines in the presence of KOH, leading to 2-phenylsulfonyl 2-haloaziridines.Starting with 2-isopropylsulfonyl aziridines, a monochloro and a dichloroaziridine are produced; the Ramberg–Bä

Secondary 2-cyano- and 2-ethoxycarbonylaziridines react with acetylenic compounds and activated vinylic chlorides to give 2-cyano and 2-ethoxycarbonyl N-vinylaziridines. The nucleophile-catalysed isomerization of these compounds generally gives α,β

Reductive cleavage of 2-phenylsulfonylaziridines with sodium amalgam provides an attractive synthetic route to 2-unsubstituted aziridines. LiAlH4 gives several compounds. DIBAH causes a sulfur-oxygen cleavage to form 2-phenylthioaziridines which are

Several 2-vinylaziridines were prepared by treating N-substituted 2-acylaziridines with phosphoranes. The stereochemistry of the ring and the double bond of the products was established from a study of their nmr spectra. The geometry of the starting
