Selective Synthesis of 3‐Chalcogenylindoles via Silver‐Catalyzed Direct Chalcogenation of Indoles with Dichalcogenides

Abstract An efficient and convenient strategy for selective synthesis of 3‐selenyl and 3‐sulfenyl indoles was developed using silver(I)nitrate as catalyst under aerobic and mild reaction conditions. This approach is scalable, economical and eco‐friendly furnishing the corresponding indoles in good to high yields in a short reaction time.
