3-((Trifluoromethyl)thio)indoles can be synthesized by a palladium(II)-catalyzed reaction of 2-alkynylaniline with trifluoromethanesulfanylamide in the presence of bismuth(III) chloride. The presence of bismuth(III) chloride is crucial for the success of this transformation, which activates the trifluoromethanesulfanylamide during the reaction.
Switchable Synthesis of 3-Cyanoindoles and 3-Amidylindoles<i>via</i>a Palladium-Catalyzed Reaction of<i>N</i>,<i>N</i>-Dimethyl-2-alkynylaniline with Isocyanide
AbstractA palladium‐catalyzed reaction of N,N‐dimethyl‐2‐alkynylanilines with isocyanides is reported, leading to the formation of 3‐cyanoindoles and 3‐amidylindoles. The isocyanide insertion is the key step during the process, and the presence of water is essential for the formation of 3‐amidylindoles.magnified image
