ChemInform Abstract: Palladium(II)-Catalyzed Annulation of Alkynes with 2-(Cyanomethyl)phenylboronates Leading to 3,4-Disubstituted 2-Naphthalenamines.
This reaction proceeds through transmetalation of the palladium(II) complex with boronates and alkyne insertion followed by nucleophilic addition of the generated alkenylpalladium(II) species to the cyano group.
