Summary: The catalytic properties of copper(II) complexes and their application in atom transfer radical addition (ATRA) reactions of alkyl halides to alkenes were studied. The complexes were effectively reduced to active copper(I) species through Eight-induced homolysis, enabling efficient catalysis of the addition reaction at room temperature. The complexes can be conveniently generated in situ for the reaction and exhibit excellent regio- and stereoselectivity.

Summary: Radical chemistry, which has a history of two centuries, focuses on radical-mediated reactions that attract organic chemists to prepare new compounds with diverse stereochemistry. The tin-based radical annulation method is commonly used for synthesizing a wide range of organic compounds with medicinal significance, following atom economical principles. Recent stereoselective tin-mediated radical cyclization reactions demonstrate the versatility of tin-based reagents in encouraging chemists to construct many other molecules of interest.

Summary: Exposure to carbon tetrachloride (CCl4) induces hepatic ductular reactions by activating Sonic hedgehog (Shh) and Yes-associated protein (Yap) signaling pathways. Inhibiting the Shh signaling with Gant61 can ameliorate liver regeneration and suppress ductular reactions, leading to decreased Shh and Yap1 signaling activities. Shh-Yap1 signaling plays a crucial role in the proliferation of ductular reaction cells in CCl4-induced liver injury.

Summary: This study investigates the mechanisms of surfactants in surfactant-in situ chemical oxidation (S-ISCO) for enhanced degradation of perchlorinated organic contaminants. The addition of Tween-80 (TW-80) or sodium dodecyl sulfate (SDS) in Fenton system resulted in a significant improvement in carbon tetrachloride (CT) removal, with TW-80 achieving a removal rate of 97.2% and SDS achieving a removal rate of 91.8%. The study also proposes possible degradation pathways of CT and assesses the impact of different solution matrixes and recovered surfactant solution on CT solubilization and removal.

Summary: This research investigated the selective separation and recovery of phosphorus from HAP and MAP using chlorination and carbo-chlorination reactions. The results showed that carbon reduction reactions played an important role in the volatilization of phosphorus, and by treating the chlorination residue with H2O, the separation of calcium, magnesium, and phosphorus could be achieved.

Summary: Inorganicsilicon compounds or products, such as silicon oxides(SiO2), metallurgical silicon (m-Si), silicon carbide (SiC),silicon halides (such as SiH n Cl4-n , n = 0-4 or SiX n , X = F, n = 2; X = Br, n = 4), silicon hydrides (SiH4 and Si2H6), nitrogen compounds (Si3N4),and the others (Si2Cl6 and Si2OCl6), have been remarkably developed in the past years. Understanding the thermodynamics of these reactions is crucial for optimizing reaction conditions and catalyst development. This study comprehensively investigates the thermodynamics of silicon-related reactions and provides valuable insights for industrial applications.

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.
