Supported palladium nanomaterials catalyzed an intramolecular CâH amination reaction to produce carbazoles in moderate to excellent isolated yields, up to 92%.
We developed palladium-catalyzed oxidative coupling of olefins with N-acyl 2-aminobiaryls through a sequence of ortho C–H bond activation/alkene insertion/reductive elimination. Furthermore, we controlled the selectivity of mono- and bis-alkenylation products with the solvent effect. The developed protocol was promising for a broad substrate scope ranging from activated olefins with a wide variety
