The use of N,N′-bis(2,6-diisopropylphenyl)dihydroimidazol-2-ylidene (SIPr) as a ligand and tBuONa as the base for sequential palladium-catalyzed intra- followed by intermolecular aryl amination enables the synthesis of N-arylated five-, six- and seven-membered nitrogen heterocycles.

An efficient, palladium-catalyzed reduction of N-(tert-butoxycarbonyl)indoles gives N-(tert-butoxy­carbonyl)indolines in good yields in the presence of polymethylhydrosiloxane (PMHS) as reducing agent at room temperature.
