Direct and Site-Selective Pd(II)-Catalyzed C-7 Arylation of Indolines with Arylsilanes.

The palladium-catalyzed oxidative arylation of indolines with arylsilanes at the C-7 position via C–H bond activation has been reported. This transformation has been applied to a wide range of substrates. It represents a facile access to C-7 arylated indolines, which can be conveniently transformed into C-7 arylated indoles.
