The electrochemical synthesis of 6‐membered rings via anodic dianilide N−N coupling is challenging due to concurring benzoxazole co‐formation. The rigidity of the a phthalic acid backbone allows a novel access to phthalazin‐1,4‐diones by N−Nbondformation using anodically generated amidyl radicals. Since conventional synthetic routes to phthalazin‐1,4‐diones require the use of toxic N,N′‐diarylhydrazines
