Abstract
In our palladium-catalyzed approach to carbazoles the central biaryl C–C bond of the framework is generated in a palladium(II)-catalyzed oxidative cyclization of an N,N-diarylamine precursor.[ 8 ] This process is based on the palladium(II)-mediated oxidative cyclization of N,N-diarylamines originally reported by Åkermark in 1975.[ 9 ] Although this process required stoichiometric amounts of palladium(II) acetate, it has found several applications in ...
