Summary: Ionic liquids (ILs) have the advantages of being low cost, eco-friendly, abundant in heteroatoms, and having excellent solubility and coordination abilities with metal ions, making them suitable precursors for fabricating metal single-atom catalysts (SACs). In this study, various metal single atoms anchored on ultrathin N-doped nanosheets were prepared using ILs and g-C3N4 nanosheets as templates. The Cu-1/NC-1000 catalyst exhibited the highest catalytic activity for benzene oxidation to phenol, with a high benzene conversion rate of 82%, phenol selectivity of 96%, and excellent recyclability.

Summary: The scarcity of fossil fuel and increasing environmental concerns have led to a growing need for the development of environmentally friendly and sustainable energy resources. Biodiesel, produced through transesterification of oils or fats with short-chain alcohol, is considered an optimal replacement for fossil-fuel based diesel due to its reproducible and eco-friendly properties. Among various catalysts, ionic liquids have shown potential as viable substitutes for conventional catalysts in biodiesel production. This paper provides a comprehensive review of the classification, synthetic schemes, and catalytic mechanism of basic ionic liquids, which have been less explored compared to acidic ionic liquids. The utilization of basic ionic liquids as catalysts for biodiesel preparation, along with the current challenges and prospects for future use, is also discussed.

Summary: In this article, a series of effective catalysts based on betaine and sulfuric or phosphomolybdic acids were obtained. These compositions were characterized and tested in the oxidation of sulfur- and nitrogenous-containing compounds by H2O2. The acidity change is non-linearly influenced by the amount of heteropolyacid (HPA), and the removal of sulfur-containing compounds is correlated with the concentration of Bronsted acid sites on the catalyst surface. On the other hand, the removal of pyridine is primarily determined by the content of heteropolyacids in the catalyst.

Summary: The chemical industry needs environmentally friendly processes, as acid-catalysed processes may cause environmental problems. The search for sustainable alternatives to conventional acids is urgent. Metal-containing ionic liquids have been of great interest to scientists due to their high Lewis acidity, which depends on the composition of the ionic liquid and the specific content of metal salt. These compounds are widely used as catalysts, co-catalysts, or reaction media in various fields of chemistry, particularly in organic chemistry. Gallium(III)- and indium(III)-containing ionic liquids effectively enhance the activity of metal salts and are easier to handle. This review emphasizes the wide range of applications and the potential of metal-containing ionic liquids, with a focus on Ga(III) and In(III), which can guide further research and synthesis of new compounds in this group.

Summary: A series of metal-free tandem reactions were conducted to synthesize pharmaceutically important 2-substituted benzoazoles using catalyst-free conditions with Et-PMO-Me-PrSO3H and SBA-15-PrSO3H as solid acids. The selectivity between 2-mercaptobenzoxazole and 2-aminobenzoazole derivatives could be altered by changing the catalyst from hydrophobic material 1a to more hydrophilic catalyst 1b. This novel and green approach provides an alternative method for synthesizing 2-substituted benzoazole derivatives.
