Nickel-Mediated Aerobic C(sp2)–Nucleophile Coupling Reactions for Late-Stage Diversification of Aryl Electrophiles

In the field of medicinal chemistry, molecular diversification is a crucial step in the discovery of new drugs. However, existing catalytic methods often face challenges when dealing with complex drug molecules, as these molecules are typically more complex than simple substrates. In particular, the formation of carbon-heteroatom (C–X) bonds is an ...

Synthesis of Molecular Borromean Links Featuring Trimeric Metallocages

The Borromean link is a topological structure composed of three independent yet interlocked rings, characterized by the fact that disconnecting any one ring results in the complete separation of the other two. This structure not only possesses aesthetic value but also holds significant research importance in molecular topology and supramolecular ch...

A Pickering-Emulsion-Droplet-Integrated Electrode for the Continuous-Flow Electrosynthesis of Oximes

Cyclohexanone oxime is a critical intermediate in the production of nylon-6, with global nylon-6 production projected to reach 8.9 million tons by 2024, leading to an increasing demand for cyclohexanone oxime. Traditional methods for synthesizing cyclohexanone oxime primarily involve the reaction of hydroxylamine (NH2OH) with cyclohexanone. However...

Capturing Aromatic Cr5 Pentagons in Large Main-Group Molecular Cages

Academic Background Transition metal clusters have long been a focus of chemical research due to their unique structures and electronic properties. Chromium (Cr), as one of the transition metals, is particularly notable for its interesting Cr-Cr bonding interactions and diverse structural arrangements. However, exploring the synthesis of polynuclea...

Synthesis and Reactivity of an Antimony(III) Dication

Synthesis and Reactivity of an Antimony(III) Dication

In enzyme catalysis, the proximity effect is a common phenomenon that forces reactions to occur by bringing two or more molecules close together. To achieve this effect, the active center requires multiple binding sites to preorganize reactants before the reaction. Although this effect has been extensively studied in enzyme catalysis, its applicati...

Late-Stage Deuteration and Tritiation through Bioinspired Cooperative Hydrogenolysis

Academic Background Hydrogenolysis, a fundamental chemical reaction that breaks chemical bonds through the addition of molecular hydrogen, is widely used in the upgrading of biomass, petroleum, and other feedstocks into high-value chemicals and fuels. Additionally, hydrogenolysis plays a crucial role in the pharmaceutical and fine chemical industri...

Certifying the Sustainability of Herding Practices in Mongolia

Background Introduction Globally, unsustainable agricultural practices have led to ecosystem degradation, particularly the destruction of grassland ecosystems due to overgrazing. Mongolia, as the world’s second-largest producer of cashmere, has significant economic, cultural, and ecological impacts from its nomadic herding practices. However, with ...

Room-Temperature Epitaxy of α-CH3NH3PbI3 Halide Perovskite by Pulsed Laser Deposition

Academic Background Metal Halide Perovskites (MHPs) have garnered significant attention in the field of photovoltaics due to their unique optoelectronic properties. In recent years, these materials have also been widely investigated for applications in light-emitting diodes, lasers, photodetectors, and spintronics. Despite notable progress in solut...

Atomic-Scale Insights into Topotactic Transformations in an Extra-Large-Pore Zeolite Using Time-Resolved 3D Electron Diffraction

Academic Background Zeolites are microporous materials with regular channel structures, widely used in catalysis, adsorption, and ion exchange. Due to their unique pore structures and chemical properties, zeolites hold significant application value in petrochemicals, environmental protection, and energy storage. However, the synthesis and structura...

Alarming Patterns of Mature Forest Loss in the Brazilian Atlantic Forest

Academic Background The Brazilian Atlantic Forest is one of the world’s biodiversity hotspots, harboring a high number of endemic species and providing critical ecosystem services. However, a long history of deforestation has reduced its original forest cover to just 24%. Despite existing legal protections, the rate of forest loss remains alarming....
