The direct visible light-mediated C-H alkylation of heteroarenes using aliphatic carboxylic acids is reported. This mild method proceeds at low catalyst loadings (0.5 mol %) and has a high functional group tolerance and a broad substrate scope. Notably, functionalization of (iso)quinoline, pyridine, phthalazine, benzothiazole, and other heterocyclic derivatives with both cyclic and acyclic primary, secondary, and tertiary carboxylic acids as well as amino and fatty acids proceeded under the standard conditions at room temperature. This protocol enables the rapid conversion of abundant feedstock materials into medically relevant “drug-like” moieties.

As a new field in POM-based functional materials, polyoxometalate-based coordination polymers (POMCPs), especially transition-metal-containing POMCPs (TM-POMCPs), have undergone substantial advancements over the past few decades for their impressive structural features and desirable properties in optics, electrochemistry, and organic catalysis. Notably, TM-POMCPs based on Keggin-type POM building blocks have attracted widespread research interest and account for more than half of the compounds reported in this class. Keggin-type POMs, strong Lewis acids with adjustable redox properties, can interact with transition metals via self-assembly in the presence of organic ligands, combining the advantages of the three constituents and resulting in many improved properties. This review focuses on Keggin-type TM-POMCPs, which are extended structures with covalently bound metal-oxide clusters with 1D chains, 2D layers, and 3D frameworks. Such coordination polymers not only enrich the structural diversity of Keggin-type POM derivatives but also provide a suitable pathway for designing functional materials with outstanding properties directed by structure?property relationship. In this review, we highlight and discuss the structural features of Keggin-type TM-POMCPs based on various dimensionalities. Furthermore, synthetic strategies and relevant applications, especially in the field of catalysis, are overviewed.

A new method for the one-step C?H amination of xanthene and thioxanthene with sulfonamides is reported, without the need for any metal catalyst. A benzoquinone was employed as a hydride (or two-electron and one-proton) acceptor. Moreover, a previously unknown and uncatalyzed reaction between iminoiodanes and xanthene, thioxanthene and dihydroacridines (9,10-dihydro-9-heteroanthracenes or dihydroheteroanthracenes) is disclosed. The reactions proceed through hydride transfer from the heteroarene substrate to the iminoiodane or benzoquinone, followed by conjugate addition of the sulfonamide to the oxidized heteroaromatic compounds. These findings may have important mechanistic implications for metal-catalyzed C?H amination processes involving nitrene transfer from iminoiodanes to dihydroheteroanthracenes. Due to the weak C?H bond, xanthene is an often-employed substrate in mechanistic studies of C?H amination reactions, which are generally proposed to proceed via metal-catalyzed nitrene insertion, especially for reactions involving nitrene or imido complexes that are less reactive (i.e., less strongly oxidizing). However, these substrates clearly undergo non-catalyzed (proton-coupled) redox coupling with amines, thus providing alternative pathways to the widely assumed metal-catalyzed pathways.

High-performance liquid chromatographic (HPLC) and subcritical fluid chromatographic (SFC) separations of the enantiomers of structurally diverse, basic ss-carboline, tetrahydroisoquinoline and benzazepine analogues of pharmacological interest were performed applying chiral stationary phases (CSPs) based on (i) neutral polysaccharides- and (ii) zwitterionic sulfonic acid derivatives of Cinchona alkaloids. The aim of this work was to reveal the influence of structural peculiarities on the enantiorecognition on both types of CSP through the investigation of the effects of the composition of the bulk solvent, the structures of the chiral analytes (SAs) and chiral selectors (SOs) on retention and stereoselectivity. As a general tendency, valid for all polysaccharide SOs studied, the increase of the concentration of the apolar component in the mobile phase (n-hexane for LC or liquid CO2 for SFC) was found to significantly increase retention, which in most cases, was accompanied with increased selectivity and resolution. In a way, similar behaviour was registered for the zwitterionic SOs. In polar ionic mode employing eluent systems composed of methanol and acetonitrile with organic acid and base additives, moderate increases in retention factor, selectivity and resolution were observed with increasing acetonitrile content. However, under SFC conditions, an extremely high increase in retention was observed with increased CO2 content, while selectivity and resolution changed only slightly. Thermodynamic parameters derived from temperature dependence studies revealed that separations are controlled by enthalpy.

The chemically exfoliated 2D-MoS2 has a mixture of 1T (metallic) and 2H (semiconducting) phases. It has shown a considerably good catalytic activity for hydrogen evolution reaction (HER), proceeding via electrochemical as well as photochemical pathways. Experimentalists have utilized triethanolamine or other sacrificial donors along with Eosin Y as a photosensitizer. But the potential of this reaction has not yet been fully explored as the sacrificial donor is wasted in the oxidation process. The oxidation cycle of this process can be used in many organic transformation(s). Herein, we report the use of the oxidative cycle for efficient cross dehydrogenative coupling (CDC) reaction with tetrahydroisoquinoline and indole substrates as well as their derivatives, parallel to HER. The reaction results in good to excellent yield of the corresponding product under visible light irradiation at room temperature. The mechanistic investigation has also been carried out. This study is a potential example of how to fully harness the oxidation and reduction cycles of many semiconductor based photocatalysts.
