Comprehensive Summary An efficient Pd/Cu‐catalyzed oxidative self‐carbonylation of arylhydrazine with CO and molecular oxygen as an oxidant to afford symmetrical biaryl ketones via C—N bond activation has been developed. In this approach, arylhydrazine hydrochlorides are used as a green arylating agent which releases nitrogen and water as byproducts. This developed protocol significantly restricts the formation of aryl iodide and homo‐coupled azobenzene products even under favorable conditions. A library of symmetrical biaryl ketones with wide functionalities was synthesized in good yields under mild conditions.
