Soluble Cu(1) and Cu(I1) triflate and perchlorate salts are efficient catalysts for the aziridination of olefins employing (N-@-tolylsulfonyl)imino)phenyliodinane, PhI=NTs, as the nitreneprecursor. Electron-rich as well as electron-deficient olefins undergo aziridination with this reagent in 55-958 yields, at temperatures ranging from -20 OC to +25 OC.

intermediates play a major role and are generated by hydrogen-atom abstraction from substrate C-H bonds or initial nitrene-addition to one of the olefinic carbons. Subsequent processes include solvent-caged radical recombination to afford the major amination and aziridination products but also one-electron oxidation of diffusively free carboradicals to generate amidination products due to carbocation

coordinating anions (WCAs) is presented. Aziridination of various olefins, such as the unreactive olefinse.g.ethylhex-2-enoate and 1-decene, with N-tosyliminophenyliodinane catalyzed by [Cu(NCR)6][Al(OC(CF3)2R′)4]2 affords very good yields (up to 96%) and high TOFs (up to 5000 h−1) under mild conditions. Using disubstituted olefins as substrates, high stereoselectivities are obtained at room temperature

Imineaziridination using diazo-compounds and catalytic quantities of metal salts and sulfides has been investigated. A range of imines derived from benzaldehyde bearing electron-withdrawing groups (N-Ts, N-SO2CH2CH2SiMe3 (SES), N-P(O)Ph2, N-CO2Bn, N-CO2But, N-CO2(CH2)2SiMe3, N-CO2C(CH3)2CCl3) were prepared and tested in the aziridination process using Me2S and phenyldiazomethane. High yields were
