The first site‐selective electrochemical alkylation of tropones is realized by reacting 2‐acetoxytropones and redox‐active‐esters. The electroreductive protocol enables the preparation of a wide range (27 examples) of mono‐ and disubstituted tropones in high yields (up to 71%) and very mild conditions. Dedicated voltammetric measurements served for the identification of 2‐acetoxytropones as a class
