A six-membered chelated iridium complex containing aza-aromatic ligand is prepared. Emission color tuning from yellow to deep red is observed for electroluminescent devices with different doping concentrations. Copyright
Palladium-Catalyzed Pyridine-Directed Regioselective Oxidative C–H Acylation of Carbazoles by Using Aldehydes as the Acyl Source
Maiti, Subhadip,Burgula, Laxminarayana,Chakraborti, Gargi,Dash, Jyotirmayee
, p. 332 - 340 (2017)
We herein report a highly regioselective reaction for the palladium-catalyzed oxidative acylation of carbazole derivatives with various aromatic and aliphatic aldehydes as the acyl source. The carbazole derivatives are N-protected with an easily removable pyridine moiety, which directs the Pd-catalyzed ortho acylation to occur at the C-1 and C-8 positions. The reactions of dibromo- and diiodo-substituted N-pyridylcarbazole derivatives, however, provide only the 1-acylated products. This method can be applied to a broad scope of substrates. A reaction mechanism has also been proposed.
