specific oxidant for PhthNH2 to create a highly chemoselective aziridination reagent. This method efficiently effects aziridination of electron-rich, electron-deficient, allylic alcohol and alkenyl bromide CC bonds in good to excellent yields. Inter and intramolecular chemoselectivity was demonstrated between electron-rich and electron-deficientalkenes by using this efficient and metal free protocol.

form aziridines is offered in terms of orbitalinteractions between the distant groups and the olefinic bond, making the latter remarkably electron deficient as evidenced by UV-photoelectron spectrosoopy. Because of the complexity of the spectra, identification of the Ip associated with the reactive π-centre was made by recourse to ab initio configuration interaction calculations for key members of the
