The process involves an anionic cyclization on a benzyne-tethered aryllithium intermediate. 2006-08-04 00:00:00 iodophenylamine 3.3 equiv aryllithium AryllithiumsThe Regioselectively Functionalized Carbazoles ether Anionic Cyclization cyclization regioselective manner electrophile fluorophenyl functionalized carbazole Dibenzothiophene thioether dibenzothiophene derivatives Dibenzofuran dibenzofuran
