A bimetallic palladium/copper catalyst system allows the highly modular synthesis of azomethines via the decarboxylativecoupling of arylhalides and α-iminocarboxylates, generated in situ from potassium α-oxocarboxylates and primary amines. The reaction proceeds already at 100 °C, a new record for redox-neutral decarboxylative cross-coupling reactions.
