Electrogenerated base (EG base) formed in a DMF–H2O (1.85 M)–Et4NOTs (0.1–0.2 M)–(Pt) system is effective for condensation of phenylacetonitrile and its related compounds with aldehydes, giving the corresponding cyanoalkylation compounds in good yields, and the concomitant dehydration of the adducts is minimized.

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
