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 and anilines to synthesize diarylamines has also been reported.
一种新型的 I2 催化的环己酮和苯胺的交叉脱氢芳构化反应，以二甲亚砜和氧气为温和的终端氧化剂，用于合成 N,N'-二芳基-o-苯二胺，这是前所未有的。为了证明所提出的机理中两个独立的脱水步骤的合理性，还报道了 I2 催化的环己烯酮和苯胺的交叉脱氢芳构化反应，以合成二芳基胺。
