Synthesis and application of 4,5-disubstituted carbazoles [PDF]
, 2023 Carbazoles are widely exploited for their interesting photophysical and electronic properties. However, (4,5-) functionalisation is challenging, and previously inaccessible through carbazole C-H activation.

Synthesis of N-acyl carbazoles, phenoxazines and acridines from cyclic diaryliodonium salts [PDF]
, 2023 N-Acyl carbazoles can be efficiently produced through a single-step process using amides and cyclic diaryliodonium triflates. This convenient reaction is facilitated by copper iodide in p-xylene, using the commonly found activating ligand diglyme.
