Iron-Catalyzed Intramolecular C(sp(2))-H Amination

摘要

The nucleophilic iron complex Bu4N[Fe(CO)(3)-(NO)] (TBA[Fe]) catalyzes the direct intramolecular C-H amination of alpha-azidobiaryls and (azidoaryl) alkenes into the corresponding carbazoles and indoles, respectively, under mild conditions and with low catalyst loadings. These features and the broad functional-group tolerance render this method a particularly attractive alternative to established noblemetal-based procedures.
