A family of congested aryliodanes based on an anti-dimethanoanthracene backbone has been synthesised and two diaryliodoniumsalts and the iodyl derivative characterised by X-ray analysis. The latter shows a rare water coordination to the iodine(V) centre in the solid state. Applications of these reagents in functional group transfer reactions are reported.

Efficient electrocatalytic aziridination of alkenes has been achieved for the first time. A structurally broad range of aziridines was easily accessed using an undivided cell operated at constant current and mediated by a catalytic quantity of n-Bu4NI. The electrocatalytic reaction also proceeded in the absence of additional conducting salt. The aziridination is proposed to follow a radical mechanism.

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.
