The reactivity of iodine(III) reagents towards nucleophiles is often associated with umpolung and cationic mechanisms. Herein, we report a general process converting a range of ketone derivatives into α‐cyclopropanated ketones by oxidative umpolung. Mechanistic investigation and careful characterization of side products revealed that the reaction follows an unexpected pathway and suggests the intermediacy of non‐classical carbocations. An impossible triangle? Iodine(III) promotes the α‐cyclopropanation of simple ketone derivatives. Mechanistic studies reveal that an unusual intermediate might be involved.
