Summary: Catalytic hydrodechlorination of 1,2-dichloroethane using Pt catalysts was studied through a synergistic approach of DFT calculations, reaction kinetics experiments, and microkinetic modeling. The reaction on Pt(111) involves multiple steps leading to the formation of ethane. Adjustments to model parameters were made to achieve good agreement between theoretical predictions and experimental results, highlighting the importance of coverage effects in catalytic reactions. Overall, the study provides valuable mechanistic insights for improving catalysts in this chemistry.

Summary: A new strategy for the direct synthesis of functionalized pyrroles from beta-amino alcohols and ynones has been demonstrated. This method proceeds in an atom- and step-economic fashion and offers the advantages of broad substrate scope, operational simplicity, and water and hydrogen gas as the sole by-products, providing an alternative and sustainable path to access functionalized pyrroles.

Summary: A Cr-modified RuO2/TiO2 catalyst was fabricated and showed enhanced activity and selectivity for 1,2-dichloroethane decomposition. The presence of Cr2O3 improved the Lewis acid sites concentration and redox ability of RuO2/TiO2, promoting the deep destruction of 1,2-DCE and inhibiting the formation of byproducts. This catalyst exhibited excellent durability under simulated conditions and can be a promising candidate for industrial CVOC catalytic degradation.

Summary: An efficient protocol for the chemoselective construction of indeno[1,2-b]pyrroles and rearranged derivatives has been reported via an N-acylation/cyclization/Wittig reaction. Mechanistic investigations revealed the crucial role of a spiro-indene-1,2'-[1,3,4]oxadiazol intermediate and its further reaction with phosphine to generate betaine, leading to the formation of the targeted heteroarenes predominantly through a Wittig reaction.

Summary: This study evaluated several reagents for the degradation of 1,2-dichloroethane (1,2-DCA), and found that the hydroxyl radicals generated by the Fenton reaction were the most suitable oxidant. Chloride, one of the final oxidized products, was observed, indicating the efficacy of the oxidation reaction. Moreover, an increase in hydroxyl radicals concentration resulted in higher degradation of 1,2-DCA.

Summary: This study used sodium persulfate activated by sodium hydroxide to remove 1,2-DCA from aqueous solutions. The results showed that by adjusting the dosing sequence and dosage of sodium persulfate and sodium hydroxide, a removal ratio of 96.24% could be achieved. A free radical reaction was the main pathway of 1,2-DCA degradation, with the superoxide radical playing a key role.

Summary: This study reports a new method to construct a three-dimensional ordered hierarchical porous carbon aerogel by directional freeze-casting and metal-organic framework-derived synergistic strategy. The as-prepared aerogel, used as a freestanding flexible electrode, shows high efficiency in ethylene production. The higher Faradaic efficiency and ethylene selectivity are attributed to the synergistic effects of directional ordered channels and hierarchical pore structures.

Summary: This study applied natural magnetite and hematite for the first time to accelerate the reductive dechlorination of 1,2-dichloroethane. It was found that low concentrations of magnetite significantly increased the rate of dechlorination, while hematite did not show a noticeable stimulating effect. Higher concentrations of iron oxides actually resulted in a weaker effect.

Summary: This study describes a novel method for preparing tetrahydropentaleno[1,2-c]pyrroles (8) through the reaction of anilines with 1-en-4-yn-3-ols in the presence of Lewis acid. The oxidation of 8 using Br2 resulted in the formation of pentaleno[1,2-c]pyrroles (10), representing the first tricyclic 5/5/5 ring with a fully conjugated system. The structures of the obtained compounds were characterized using spectroscopic methods, with compounds 8a,b and 10c further confirmed by X-ray crystallography.

Summary: The influence of substituents on the pyrrole ring and at the triple bond on the formation of fused pyrrolooxazines from 1H-pyrrol-2-ylmethanols and propargyl chlorides has been studied both theoretically and experimentally. Quantum-chemical calculations (CBS-Q//B3) were used to evaluate the energy characteristics of the reaction. A one-pot transition metal-free synthesis of substituted 3-methyl-1H-pyrrolo[2,1-c][1,4]oxazines in good yields has been achieved in the superbasic system NaOH/DMSO.

Summary: In this study, a low-metal iron-supported catalyst (Fe20/NC-Mg) was reported for the efficient synthesis of quinoxaline compounds, using water as a solvent and without additional bases. The synergistic effect of FeNx site and Mg (OH)2 nanorods in the catalyst played a key role in achieving high yields (82-91%) in 16 examples. The gram-level synthesis and reusability of the catalysts after four cycles demonstrated its industrial application potential.
