Rhodium(III)-catalyzed directed C–H benzylation and allylation of indoles with organosilicon reagents

Rhodium(III)-catalyzed C2-benzylation and allylation of indoles with organosilicon reagents via chelation-assisted C–H activation has been developed. This protocol demonstrates a board substrate scope, tolerates a broad range of synthetically useful functional groups, and enables a straightforward route to C2-benzyl- and allylindole derivatives.
