Carbazole derivatives

Synthesis of Carbazoles and Dibenzofurans via Cross-Coupling of o-Iodoanilines
o-Iodophenols with Silylaryl Triflates. — A simple and efficient one-pot,
04- 123 and
two-step procedure to carbazole and dibenzofuran ring systems includes cross-coupling
of iodoanilines or o-iodophenols with arynes followed by palladium-catalyzed intermolecular arylation. The reaction tolerates various functional groups and allows to prepare a number of new and multisubstituted carbazoles and dibenzofurans in good to
excellent yields. — (LIU, Z.; LAROCK*, R. C.; Org. Lett. 6 (2004) 21, 3739-3741;
