Hypervalent iodine‐guided electrophilic substitution (HIGES) was described previously for the para‐selective benzylation of aryl‐λ3‐iodane diacetates. To make our methodology more accessible to the synthetic community, a procedure was developed in which the benzylation product can be afforded from an aryl iodide by an in situ oxidation with an overall higher yield for most substrates.
