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.

Look, no metal: A metal‐free catalytic procedure for aziridination of alkenes using tetrabutylammonium iodide as the catalyst, m‐chloroperoxybenzoic acid (mCPBA) as the terminal oxidant, and N‐aminophthalimide as the nitrenium precursor has been developed (see scheme; right: X‐ray structure of one of the products). Control experiments suggests that the active oxidant is in situ generated hypoiodous
