Pd(II)-catalyzed intramolecular amination of arenes using either Ce(SO4)2 as a one- or N-fluoro-2,4,6-trimethylpyridinium triflate as a two-electron oxidant tolerates a wide range of functional groups including acetyl, cyano, and nitro. This catalytic reaction allows expedient syntheses of broadly useful substituted indolines or indoles.
