catalyzes the aziridinationreactions of enol silyl ethers with tosylimino(iodo)benzene (PhINTs) in acetonitrile to give α-N-tosylamido ketones by subsequent aziridine ring opening. Olefins are converted into aziridines by 5 mol% of this catalyst system. Both reactions afford the corresponding products in moderate to good yields. In the presence of chiral ligands asymmetric aziridinations have been achieved
(t-BuOI) was found to be a powerful reagent for synthesis of aziridines from olefins and sulfonamides. The aziridination of olefins was achieved by using sulfonamides with t-BuOI. Our preliminary findings represent the example of metal-free aziridination of olefins with readily accessible sulfonamides as a nitrogensource.

The reaction of Simmons–Smith carbenoids with imines in the presence of sulfides provides N-(p-toluenesulfonyl)- and N-[(1,1,1-trimethylsilyl)ethyl]sulfonyl-substituted aziridines in high yield.
