Abstract 2‐Aryl‐substituted nitriles were prepared in good to excellent yields in a one‐pot reaction by the reaction of benzyne, generated using neutral conditions from (phenyl)[o‐(trimethylsilyl)‐phenyl]iodonium triflate, and 2‐lithionitriles. 3‐Keto nitriles substituted at the 2‐position were obtained in good yields when these reactions were trapped with acid chlorides. The mechanism of the benzyne
