Palladium‐Catalyzed Direct and Site‐Selective Desulfitative Arylation of Indoles with Sodium Sulfinates

Abstract

Abstract An efficient method was developed for the desulfitative arylation of indoles with sodium sulfinates using palladium as catalyst and copper chloride dihydrate as oxidant. The direct arylation occurred exclusively in the C‐2 position of indoles and proceeded well for a range of different substrates.
