Iodoalkoxylation of oxindole with alcohols was achieved by using a hypervalentiodine species in combination with iodine under metal‐free conditions. This method is useful for the synthesis of 3‐alkoxy oxindole, 5‐iodo‐3‐alkoxy oxindole and 5‐iodo‐3,3‐dialkoxy oxindole by sequentially in moderate to good yields.
