Ruthenium Catalyzed C-H Selenylations of Aryl Acetic Amides and Esters via Weak Coordination.

An efficient ruthenium-catalyzed direct C-H selenylation of aryl acetic amides and esters has been achieved via distal weakly coordination. Notable features of this protocol including broad substrate scope, wide functional group tolerance, and good regioselectivity. In addition, diaryl disulfides were also successfully applied to this reaction under slightly modified conditions.
