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.

Herein, the first elemental sulfur-promoted aerobic dehydrogenative aromatization of cyclohexanones is described that provides novel access to synthetically useful o-arylenediamines. This protocol complements previous palladium- A nd iodine-catalyzed diarylamine formation from cyclohexanones and anilines.

An efficient palladium-catalysed amination of aryl chlorides in presence of 1,3-bis-(2,6-diisopropylphenyl)imidazolinium chloride
Shen, Huafeng,Zhang, Zhong-Ping,Li, Jing-Hua
experimental part, p. 163 - 166 (2010/07/08)
1,3-bis-(2,6-diisopropylphenyl)imidazolinium chloride (SIPr·HCl), a precursor for an N-heterocyclic carbene, was examined as a pro-ligand in C-N coupling reactions. Thus SIPr·HCl associated with a palladium catalyst was found to be efficient for the amination of aryl chlorides under mild conditions.
