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.

Summary: A method for the synthesis of enantiopure eight-membered nitrogen heterocycles has been developed through diastereoselective cross-coupling of 2-iodobiphenyls with 2-bromobenzylamines. The products provide a new type of chiral scaffold with easy modification and high configurative stability, which could be used in asymmetric synthesis. Palladacycles formed via the C-H activation of 2-iodobiphenyls act as the intermediates, offering a new strategy for synthesizing medium-sized ring compounds.

Summary: Sulfonyl fluorides have been identified as powerful click electrophiles for Pd-catalyzed Suzuki-Miyaura cross-coupling, occurring selectively in the absence of base and even in the presence of strong acids. Mechanistic experiments and DFT calculations suggest that oxidative addition at the C-S bond followed by desulfonation facilitate transmetalation in this desulfonative cross-coupling reaction.

Summary: A nickel/dppf catalyst system successfully achieved Suzuki-Miyaura cross-coupling reactions of certain chloropyridines and chloroquinolines but not others, due to differences in the reaction mechanism. Chloropyridines rapidly undergo oxidative addition to the catalyst, while alpha-halo-N-heterocycles form catalytically inactive dimeric nickel species.

Summary: This review focuses on the intrinsic role of carbon materials in carbon-hybridized hydroxides (CHHs), particularly regarding the interface chemistry and engineering strategy between the two components. The fundamental effects of carbon materials in enhancing charge/mass transfer kinetics are analyzed, along with the surface-guided/confined effects in modifying morphology and tailoring hydroxides. Methods for constructing stable and robust solid-solid heterointerfaces are summarized, and the application of CHHs in energy conversion/storage is demonstrated. Additionally, methodologies for investigating the hybridization electron configuration between two components are identified. The perspective and challenges of using CHHs in energy-related applications are outlined.

Summary: In this study, a novel liquid-liquid-solid system is reported to regulate the selectivity of benzyl alcohol electrooxidation. The selectivity of benzaldehyde increases 200-fold from 0.4% to 80.4% compared with the liquid-solid system at a high current density of 136 mA cm(-2), which is the highest one up to date. In the tri-phase system, the benzaldehyde peroxidation is efficiently suppressed, with the conversion of benzaldehyde being decreased from 87.6% to 3.8%. The as-produced benzaldehyde can be in situ extracted to toluene phase and separated from the electrolyte to get purified benzaldehyde. This strategy provides an efficient way to enhance the selectivity of electrocatalytic cascade reactions.

Summary: This study proposes a metal oxide space-confined strategy to optimize the hierarchical structure of porous carbon cathodes, resulting in improved electrochemical performance of zinc-ion hybrid capacitors (ZIHC). By using low-cost aromatic hydrocarbons as precursors, 3D graphene-like porous carbon nanosheets (3DPC) doped with O and S heteroatoms are synthesized. The well-defined hierarchical porosity of 3DPC, coupled with rich O and S heteroatoms, enables effective ion transport and ion capture, leading to desirable capacity, rate capability, and cycling stability in aqueous ZIHC assemblies. Furthermore, the remarkable electrochemical performance of 3DPC is well-preserved in a quasi-solid-state ZIHC device under various harsh bent states, demonstrating its potential application in flexible and wearable energy storage.

Summary: Localized water-in-salt (LWIS) electrolytes are a promising candidate for high-voltage aqueous electrolytes with low viscosity and low salt content. The choice of an effective diluent is crucial for the properties of LWIS electrolytes. By identifying the donor number of solvents as a descriptor of solvent-salt interaction intensity, organic diluents that have minimal impact on the solvation microenvironment and intrinsic properties of the original high-salt electrolyte can be screened. This allows for the construction of a novel low-viscosity electrolyte with a low dosage of LiNO3 salt and well-preserved intrinsic Li+-NO3 (-)-H2O clusters, leading to improved performance in aqueous supercapacitors.
