Pd(II)-Catalyzed Amination of C−H Bonds Using Single-Electron or Two-electron Oxidants

Abstract

Pd(II)-catalyzed intramolecular amination of arenes is developed using either a one- or two-electron oxidant. The reaction protocol tolerates a wide range of deactivating groups including acetyl, cyano, and nitro groups. This catalytic reaction allows expedient syntheses of broadly useful substituted indolines or indoles.
