Novel enabling synthetic methodology
Researching metal- and photo-catalyzed methods to promote S_N_Ar reactions between thiols and aryl halides, Dawei Ma and coworkers, report an S_N_Ar reaction of thiols with most electron-poor aryl halides taking place at room temperature under the action of K_2_CO_3_ and DMAc (http://doi.org/10.1039/D3GC02066E). Critically, two more powerful oxalic diamide ligands were identified to facilitate the Cu-catalyzed coupling reactions with low catalytic loadings. Jin-Quan Yu, Zhong Jin and coworkers develop an efficient macrocyclization strategy via Pd-catalysed intramolecular meta-C–H olefination using a practical indolyl template. This approach has been successfully employed to access macrolides and coumarins (https://doi.org/10.1039/D3SC01670F). Xiao-Feng Wu and coworkers, develop a two-step protocol to access 1,2-diarylethanones, involving site-selective C(sp^2^)–H thianthrenation and carbonylation of arenes under mild conditions (https://doi.org/10.1039/D3SC02402D). Jinshuai Song, Hai-Chao Xu and coworkers, develop a photoelectrocatalytic C–H amination approach for synthesizing anilides via the C–H/N–H coupling of arenes and carbamates (https://doi.org/10.1039/D3GC02126B). Jing-Hao Qin, Chong-Hui Xu, Yang Li and Jin-Heng Li and coworkers, present an elegant rhodium-catalyzed electrochemical [2 + 2 + 2] cyclotrimerization of 1,3-butadiynes, showcasing a method for the regioselective synthesis of structurally diverse hexasubstituted arenes (https://doi.org/10.1039/D3GC02831C).

Chunlan Song, Jiakun Li and coworkers, report an electrochemical ring-opening 1,3-dihydroxylation of arylcyclopropanes with H_2_O, enabling the direct formation of 1,3-diols through controlled electrochemical C–C bond cleavage of arylcyclopropanes with H_2_O as the ultimately green hydroxyl source (https://doi.org/10.1039/D3GC02283H).
Sustainable and green chemistry
Qixue Qin and Ning Jiao and coworkers, present a novel and efficient approach for the oxidative rearrangement of cyclobutenones, by utilizing I_2_ as a catalyst and dimethyl sulfoxide (DMSO) as a greener oxidant and source of oxygen (https://doi.org/10.1039/D3GC01756G). Si-Shun Yan, Yong-Yuan Gui and Da-Gang Yu, and coworkers, report a photocatalytic defluorocarboxylation using formate salts as both a reductant and a carbon dioxide source. This transition metal-free strategy provides a mild, efficient, and sustainable approach for accessing a series of valuable aryl acetic acids, such as flurbiprofen (https://doi.org/10.1039/D3GC01299A). Chen-Guo Feng, Yingbin Liu, Guo-Qiang Lin and coworkers, report a convenient method for synthesizing aryl-containing trisubstituted alkenes through direct alkylation of alkenes under solvent-free and catalyst-free conditions (https://doi.org/10.1039/D3GC02685J). Liyan Song, Ran Lin and Rongbiao Tong and coworkers, report the inaugural green oxidation of amides and aldehydes (alongside NaN_3_) using oxone and halide to yield the N-halo amides and acyl azides, the key intermediates for Hofmann and Curtius rearrangements respectively (https://doi.org/10.1039/D3GC04355J).
Electrochemical energy storage and conversion
Li Xiao, Lin Zhuang and Héctor D. Abruña, and co-workers, found that the degradation of the ionomer in an anion exchange membrane fuel cell (AEMFC) is considerably more severe than that of the membrane under realistic operation (https://doi.org/10.1039/D3SC03649A). Wei Luo and co-workers, found that a sulphate functionalized Ru catalyst (Ru–SO_4_) exhibited remarkable electrocatalytic performance and stability toward alkaline hydrogen oxidation reaction (https://doi.org/10.1039/D3SC02144K). Huayi Yin and co-workers, systematically summarize the recycling methods using salts as agents to enable the conversion of cathode materials of spent lithium-ion batteries (LIBs), in a review article (https://doi.org/10.1039/D2GC04620B). Jun Huang and Shengli Chen and co-workers, reveal that electrostatic interactions play a decisive role in coupled charge transfer and Li+ segregation in the LiFePO_4_ cathode material (https://doi.org/10.1039/D3SC04297A). Jiangfeng Qian and co-workers, propose a phenazine-mediated chemical sodiation strategy to precisely synthesize a Na-enriched Na_4_V_2_(PO_4_)3 cathode under the guidance of a redox-potential-matching principle, and significantly boost the energy density of sodium-ion batteries (SIBs) (https://doi.org/10.1039/D3SC03498D). Xiangjun Pu, Mingyue Ding and Zhongxue Chen and coworkers, propose delta-oxovanadium phosphate as the cathode material for aqueous zinc-ion batteries (https://doi.org/10.1039/D3SC02382F).

Synthesis and studies of functional molecules: impacts on biology, drug discovery, and the environment
In molecular imaging, recognition elements for various targets play a crucial role in high-performance imaging. The review by Bingqian Lin and coworkers, provide a comprehensive summary of engineered aptamers for molecular imaging, including various design strategies, a wide range of targets ranging from cell membrane proteins, nucleic acids, organelles, metabolites, to metal ions, as well as different imaging modalities (https://doi.org/10.1039/D3SC03989G). In an effort to develop dehydroalanine (Dha)-modified strategies, Yanmei Li and colleagues, report a photoinitiated 1,3-dipolar cycloaddition reaction between Dha and 2,5-diaryl tetrazoles (https://doi.org/10.1039/D3SC02818F). The reaction they worked on exhibited complete site-specificity in the modification of thiostrepton in high yields, providing a chemoselective approach for precise functionalization of proteins. With fluorogenic properties, the reported photo-controllable methodology could be applied to live cell imaging, thus expanding the practicality of the Dha modification methodology. Yanfeng Dang, Xiu-Qin Dong and Chun-Jiang Wang and coworkers, report a new strategy that enables, for the first time, the atroposelective synthesis of axially chiral N,N′*-*pyrrolylindoles via de novo indole formation catalyzed by chiral phosphoric acid (CPA). This work also provides a preliminary investigation on the biological activity of these N,N′-pyrrolylindoles and their low IC_50_ value toward different cancer cell lines suggests their encouraging potentials in drug discovery (https://doi.org/10.1039/D3SC03686C). Xiaoguang Lei and coworkers, disclose the first total syntheses of a family of alkaloids, including picrasidines G, S, R, and T and related derivatives, in a concise manner. The success of this work is attributed to an innovative late-stage aza-[4 + 2] cycloaddition, which also provides synthetic evidence for the proposed biosynthetic pathway of ITHQ-type bis-β-carboline alkaloids that have appealing biological activities (https://doi.org/10.1039/D3SC03722C). Twisted polyarenes with persistent chirality are desirable but their synthesis has remained a challenge. Zhe Sun and Jishan Wu and coworkers, report highly twisted 1,2:8,9-dibenzozethrene and its vertically fused dimers and trimers by a “one-pot” nickel-catalyzed cyclo-oligomerization reaction. This study also offers an efficient way to access highly twisted polyarenes with enantiomers that can be separated with either left-handed or right-handed helicity (https://doi.org/10.1039/D3SC02285D). Radiocesium ions are a major species in radioactive wastewater, therefore, efficient treatment and isolation methods for Cs ions are highly sought. Xiaodong Shi and coworkers, report the preparation of a covalently tethered isoguanosine self-assembled pentamer that could selectively extract Cs ions with good reusability. This new extractor served as a new platform for the treatment of radiocesium in an environmentally benign manner (https://doi.org/10.1039/D3GC02932H).
This collection continues to amass new and exciting research as more articles are being accepted from WHU researchers and associates. We wish WHU a happy anniversary and hope our readers have a good time reading the collection.
