Construction of Benzo-Fused Polycyclic Heteroaromatic Compounds through Palladium-Catalyzed Intramolecular C-H/C-H Biaryl Coupling

Yuji Nishii et al.

Summary: Dibenzo-fused five-membered heteroaromatic compounds, such as dibenzofuran, carbazole, and dibenzothiophene, are important structural units in various polycyclic heteroaromatic compounds. The intramolecular C-H/C-H biaryl coupling of diaryl (thio)ethers and amines based on palladium(II) catalysis under oxidative conditions is an effective method for their construction. This mini-review briefly summarizes representative examples of constructing structurally intriguing pi-extended polycyclic heteroaromatics through catalytic coupling reactions.

Iron-catalyzed reductive cyclization of nitroarenes: Synthesis of aza-heterocycles and DFT calculations

Christine Tran et al.

Summary: We developed a new approach for synthesizing substituted dihydrobenzo[c]carbazoles and indoles through iron-catalyzed hydrogen transfer reduction of nitroarenes followed by intramolecular cyclization. This strategy involves the use of a Knolker-type catalyst, Cs2CO3 as the base, and benzyl alcohol as the hydrogen donor. We synthesized 30 examples of aza-heterocycles with moderate to excellent yields using this approach. DFT calculations suggest an anionic mechanism for the reaction pathway.

Solvent Effects on the Photoinduced [6?]-Electrocyclization Reactions of Mono-, Di-, and Trisubstituted Arylamines: Photophysical, Preparative Photochemistry, and Mechanistic Investigations

Ivan E. Romero et al.

Summary: This study investigates the effects of substituents and solvents on the spectroscopic behavior and the photoinduced [6x]-electro-cyclization reaction of substituted triphenylamine derivatives. It is found that triphenylamines with electron-donor substituents produce substituted exo/endo carbazole derivatives, while those with electron-withdrawing substituents form charge transfer complexes (CTCs) instead of carbazoles. The photoreaction is favored by weak electron-acceptor groups in polar solvents. The absorption and fluorescence spectra of these derivatives show dependence on solvent polarity.

Iodine-Catalyzed Annulation Reaction of Ortho-Formylarylketones with Indoles: A General Strategy for the Synthesis of Indolylbenzo[b]carbazoles

Sundaram Suresh et al.

Summary: The iodine-catalyzed cascade reaction between ortho-formylarylketones and indoles for the synthesis of indolylbenzo-[b]carbazoles is described. The reaction involves two successive nucleophilic additions of indoles to the aldehyde group of ortho-formylarylketones, while the ketone functionality does not participate in the nucleophilic addition and undergoes only Friedel-Crafts-type cyclization. The efficiency of this reaction is demonstrated with gram-scale reactions using various substrates.

Bronsted Acid-Catalyzed Reaction of N-arylnaphthalen-2-amines with Quinone Esters for the Construction of Carbazole and C-N Axially Chiral Carbazole Derivatives

Mingliang Zhang et al.

Summary: We demonstrated an efficient synthetic method for carbazole derivatives using N- arylnaphthalen-2-amines and quinone esters catalyzed by Bronsted acid. The reaction yielded a series of carbazole derivatives in good to excellent yields under mild conditions. Additionally, using chiral phosphoric acid as a catalyst, a series of C-N axially chiral carbazole derivatives were successfully constructed with moderate to excellent atroposelectivities, providing a novel strategy for the atroposelective construction of C-N axially chiral compounds.

Synthesis and photophysical properties of fluorescent 8,9-diarylbenzo[def]carbazoles

Huan-Chang Hsiao et al.

Summary: We report the synthesis and photophysical properties of N-acyl and N-free 8,9-diarylbenzo[def]carbazoles. The 8,9-diarylbenzo[def]carbazoles show lower energy levels and smaller HOMO/LUMO gap compared to the parent benzo[def]carbazole, and the N-unprotected ones show more red-shifted fluorescent emission compared to the N-acyl ones. These 8,9-diaryl substituted benzo[def]carbazoles in CHCl3 exhibit absorption and emission maxima in the ranges of 278-350 and 365-426 nm, respectively, with high quantum yields (phi(F)) up to 0.62.

Summary: An efficient Friedel-Crafts-type reaction followed by electrocyclization cascade has been developed using readily available starting materials, ethanol as a solvent, and Bronsted acid as a catalyst under an air atmosphere. The strategy has been successfully applied to the synthesis of 2-(2-aminophenyl)-9H-carbazole with excellent regioselectivity, functional group tolerance, and scalability. Additionally, the one-pot synthesis of quino[3,4-a]carbazoles has been achieved, demonstrating the broad synthetic utility of this strategy for the synthesis of valuable heteroaryl-annulated [a]carbazoles.

Review on Carbazole-Based Hole Transporting Materials for Perovskite Solar Cell

Krishnapriya Radhakrishna et al.

Summary: Solar cells made of organic-inorganic metal halide perovskite have the potential to replace traditional silicon-based solar cells, but their efficiency is a major hurdle in commercialization. The use of suitable organic hole transporting materials can improve the efficiency of perovskite solar cells. Spiro-OMeTAD is the standard hole transporting material used, but its complex synthesis and purification steps make it cost-ineffective. Recently, hole transporting materials made of organic small molecules, such as carbazole, have shown better photovoltaic properties and cost-effectiveness. This review focuses on the design and synthesis strategies of carbazole-based hole transporting materials and evaluates their performance in perovskite solar cells.

Insight into the Diindolo[3,2-b:2′,3′-h]carbazole Core as an Air-Stable Semiconductor for OTFTs

Roger Bujaldon et al.

Summary: This study presents the synthesis of five diindolo[3,2-b:2 ',3 '-h]carbazole derivatives and their application in organic thin-film transistors. The single-crystal structures of these compounds were elucidated by powder X-ray diffraction analysis, providing insight into the intermolecular arrangement. By fine-tuning the length of alkyl chains and the type of passivation layer, a range of mobility values from 10(-6) to 10(-3) cm(2) V-1 s(-1) was achieved. Remarkably, these devices exhibited excellent temporal and air stability with a shelf lifetime of up to several years, confirming the potential of this research.

Gold-Catalyzed Cyclizations and [3+2]-Annulation Cascades between 1,5-Diyn-3-ols and Nitrones to Construct Carbazole Frameworks

Sudhakar Dattatray Tanpure et al.

Summary: Gold-catalyzed cascade reactions between 1,5-diyn-3-ols and nitrones have been developed for the synthesis of carbazole derivatives. This reaction provides a facile approach for the synthesis of polyaromatic compounds containing carbazole subunits. The unexpected oxoarylation reaction, instead of the known oxidative Mannich reaction for but-1-yn-4-ols, is attributed to the presence of a second alkyne in 1,5-diyn-3-ols, which weakens the bonding between gold and this alkyne and restricts the conformational flexibility of the tethered alcohol.

Hydrogen-Borrowing Reduction/Dehydrogenative Aromatization of Nitroarenes through Visible-Light-Induced Energy Transfer: An Entry to Pyrimidoindazoles and Carbazoles

Zhonghua Qu et al.

Summary: In this study, a novel visible-light-induced protocol for hydrogen-borrowing reduction/dehydrogenation aromatization/cyclization of nitroarenes by energy transfer is described. The protocol does not require additional oxidants, hydrogen acceptors, and hydrogen evolution metal catalysts. Mechanistic studies showed that the hydrogen-borrowing reduction/dehydrogenative aromatization process is initiated by the formation of active singlet species through efficient energy transfer of excited Ir[dF(CF3)ppy]2(dtbpy)PF6 to nitroarenes.

Summary: The photoreactivity of triphenylamine in homogeneous media was investigated using laser flash photolysis spectroscopy and preparative experiments to evaluate the photophysical and photochemical behavior of transient N-phenyl-4a,4b-dihydrocarbazole (DHC0) under polar and non-polar solvents. The kinetic parameters of DHC0, including lifetime and rate constants, were measured, and its intermediacy in the co-oxidation of nucleophilic substrates was studied.
