Rh(I)-catalyzed decarbonylation synthesis of carbazoles via C-N cleavage
A one-pot Rh(I)-catalyzed synthesis of 9-H carbazoles via C-N bond cleavage by activation of aldehyde C-H bonds is reported. This protocol offers good yields and tolerates a broad range of functional groups. Based on the extensive control experiments, we propose a plausible decarbonylation mechanism.

Synthesis of Carbazoles by a Diverted Bischler-Napieralski Cascade Reaction
An unforeseen twist in a seemingly trivial Bischler-Napieralski reaction led to the selective formation of an unexpected carbazole product. The reaction proved to be general, providing access to a range of diversely substituted carbazoles from readily available substrates. Judicious variation of substituents revealed a complex cascade mechanism comprising no less than 10 elementary steps, that could be diverted in multiple ways toward various other carbazole derivatives.

A novel bipolar host material based on carbazole and 1,3,5-triazine with an extremely low efficiency roll-off for green PhOLEDs
In this contribution, a novel bipolar host material, namely CzTrz, consisting of a phenylcarbazole for hole transport and a diphenyltriazine for electron transport, was synthesized and investigated. Besides, a carbazole-based unipolar host BCz2 was designed as a reference. Both CzTrz and BCz2 display good thermal stability, high triplet energy level (ET) and suitable frontier orbital levels. Green PhOLEDs hosted by CzTrz and BCz2 show turn-on voltage (Von) of 3.5 and 3.8 V, maximum luminance (Lmax) of 30,280 and 35,050 cd m?2, and maximum external quantum efficiency (EQEmax) of 15.49 and 11.84%, respectively. Remarkably, the CzTrz-based device reveals an extremely low efficiency roll-off at the high luminance, for example, 15.35% at 1000 cd m?2 and 13.85% at 5000 cd m?2, corresponding to merely 0.9% and 10.6% roll-off percentage, which is among the best results ever reported as green bipolar hosts.

Concatenating Suzuki Arylation and Buchwald–Hartwig Amination by A Sequentially Pd-Catalyzed One-Pot Process—Consecutive Three-Component Synthesis of C,N-Diarylated Heterocycles
The concatenation of Suzuki coupling and Buchwald-Hartwig amination in a consecutive multicomponent reaction opens a concise, modular and efficient one-pot approach to diversely functionalized heterocycles, as exemplified for 3,10-diaryl 10H-phenothiazines, 3,9-diaryl 9H-carbazoles, and 1,5-diaryl 1H-indoles, in high yields starting from simple staring materials. Moreover, this one-pot reaction is a sequentially palladium-catalyzed process that does not require additional catalyst loading after the first coupling step.

An effective and operationally simple protocol is reported for the synthesis of versatile carbazoles. With water as a co-solvent, visible-light rather than various metals is used to facilitate the conversion of readily available 2-azidobiphenyls under mild conditions. Various functionalized bioactive natural alkaloids, such as glycoborine, clausine C, clausine L, clausine H and clauszoline K, were synthesized efficiently with nitrogen as a sole byproduct. The reaction could be performed in water, acidic or alkaline buffer solutions, showing its potential for applications in biochemistry.

Kinesin spindle protein (KSP) inhibitors with 2,3-fused indole scaffolds
Mitotic kinesin spindle protein (KSP) is involved in the assembly of the bipolar spindle during cell division. On the basis of a common 2,3-fused indole substructure within the complex frameworks of terpendole E and other KSP inhibitors, the carbazoles with a bulky alkyl group were identified as a novel KSP inhibitory scaffold. Additionally, among several naturally occurring cell growth inhibitors with 2,3-fused indole structures,β-carboline alkaloids, harman and harmine, showed moderate inhibition of KSP.

Synthesis of carbazoles by intramolecular arylation of diarylamide anions
(Chemical Equation Presented) The synthesis of a series of substituted 9H-carbazoles by the photostimulated SRN1 substitution reaction with diarylamines as starting substrate was performed. The diarylamines were obtained by two approaches, the Pd-catalyzed reactions (Buchwald-Hartwig) or Cu-catalyzed reactions of 2-haloanilines with aryl halides, or 2-bromoiodobenzene with anilines, with moderate to very good isolated yields (45-89%). Through an intramolecular C-C bond formation of diarylamines by the SRN1 mechanism, carbazoles were achieved. These reactions proceeded synthetically in very good to excellent yields (81-99%) in liquid ammonia and DMSO. The reaction of N-(2-bromophenyl)-2-phenylbenzenamine gave 1-phenyl-9H-carbazole (38%) and the isomer 9H-tribenz[b,d,f]azepine (58%). By using this methodology, 9Hcarbazoles, substituted 9H-carbazoles, benzocarbazoles, and even 3,3′-bi(9H-carbazole) were obtained by a double SRN1 reaction with benzidine.
