A novel I2-catalyzed cross-dehydrogenative aromatization of cyclohexanones and anilines to synthesize N,N′-diaryl-o-phenylenediamines has been unprecedentedly developed with dimethyl sulfoxide and oxygen employed as mild terminal oxidants. To prove the rationality of the two separate dehydration steps of the proposed mechanism, a resulting I2-catalyzed cross-dehydrogenative aromatization of cyclohexenones
