α-Aryl-α-aminocarbonyloxime O-pentafluorobenzoates are found to be promising precursors for synthesis of 2, 3-disubstituted indole derivatives catalyzed by PdCl2 (MeCN) 2 in the presence of MgO as a base. The reaction is supposed to proceed via intramolecular aromatic C–H amination of a vinyl nitrene–palladium intermediate.
