Convenient Access to C4‐Dicarbonylation of Anilines by Iodine‐Promoted Oxidative Cross‐Coupling Reactions

An innovative route for the construction of C4-dicarbonylation of anilines from simple and readily available anilines and phenyl acetylene has been developed. The iodine-promoted oxidative cross-coupling reaction performed well and the highlight of this protocal was not N−H functionalization but C−H functionalization of unprotected anilines.
