We herein report a robust catalyst‐free cross‐coupling between ArI(OAc)2 and α‐stannyl nitriles, aided by TMSOTf. The transformation introduces a cyanoalkyl group to the ortho position of ArI(OAc)2 and simultaneously reduces the aryl iodine(III) to iodide, thus providing α‐(2‐iodoaryl) nitrile as the product. This transformation could be completed within 5 min at −78 °C and features superb functional‐group
