标题：pd-catalyzed c(sp2)–h aminocarbonylation using the langlois reagent as a carbonyl source
abstract: a pd-catalyzed c(sp2)–h aminocarbonylation of aryl carboxamides assisted by an n,s-bidentate directing group was developed, in which cheap and stable sodium trifluoromethanesulfinate was first utilized as a carbonyl source. the reaction can be applicable to a wide range of carboxamides with good functional group tolerance and afford isoindole-1,3-diones in moderate to good yields
