From aldehydes or cyclic ketones, diazoalkanes, and tertiary phosphanes, olefins may be prepared according to Equation (a) with MTO as catalyst. In particular, diazoacetates -malonates (R2, R3H, CO2,Et, 2 × CO2 Me) can transformed into aliphatic aromatic (R1iPr, trans-PhCHCH, Ph, 4-NO2C6H4, etc.). Readily accessible starting materials, easy handling, mild reaction conditions, good yields characterize the new synthesis method. (R′Ph, 3-C6H4SO3Na, nBu.)
Under redox-neutral conditions, rhodium(III)-catalyzed C–H annulation of N-tert-butyl-α-arylnitrones with internal alkynes has been realized for the synthesis indenones under mild conditions. This reaction proceeded in moderate to high yields and good functional group tolerance.
Foreign atom doping is known to not only modify the electronic structure but also improve intrinsic activity of catalysts. Herein, we fabricate three-dimensional (3D) self-supporting nanoporous cobalt–aluminum intermetallic (np-Co(Al)) through dealloying Al90Co10 master alloy in situ introduce Al element into precursor. The dopant determined be insensitive S vapor beneficial generate numerous Al-doped CoS2 nanowires (Al-CoS2 NWs) when they were subjected solid–vapor sulfurization treatment....
Abstract Developing noble‐metal‐free electrocatalysts with excellent activity and stability for the hydrogen evolution reaction (HER) oxygen (OER) is essential promoting generation of H 2 by electrocatalytic water splitting. Herein, a novel 3D self‐supported Ni−Mo−S nanowire network film electrode was prepared facile electroplating nickel−molybdenum on nickel foam followed sulfurization as bifunctional catalysts both HER OER. Electrochemical measurements reveal that superb high catalytic...

A highly stereoselective annulation proceeded successfully to afford chiral thiazolo pyrones with excellent ee (up 99%) and d.r. >20 : 1). Both enantiomers can be obtained. In the presence of oxygen (O<sub>2</sub>), oxidant<bold>O-1</bold>can used in a catalytic amount (even low 2 mol%).
Silicon (Si) has been ascertained as one of the most desirable anode candidates for sodium-ion batteries (SIBs), ascribed to its sizeable theoretical capacity and abundant resource. However, inherent electrochemical inertness crystalline Si against sodium impedes practical use. Herein, lattice-coupled nanoparticles are uniformly distributed onto delaminated MXene (d-MXene) further tightly confined by hard carbon (HC), consequently forming a 3D cross-linked (Si/d-MXene)@HC architecture an...
An efficient strategy was proposed to prepare crystalline borophene quantum dots with two-photo fluorescence and their derivative boron nanospheres.
It is well known that the oxygen evolution reaction (OER) predominant to restrict hydrogen production efficiency from water splitting. Herein, a porous spinel oxide, CuCo2O4, with abundant defects successfully developed via facile strategy (alloying–dealloying–annealing) as an efficient and economical electrocatalyst for OER. Profiting well-structured porosity, cation (Cu vacancies) induced by hereditary Mn doping, anion (oxygen vacancies), OV-np-Cu10Co20(Mn) gives smaller OER overpotential...

Mangrove ecosystems play a crucial role in coastal environment by stabilizing shorelines, reducing erosion, and providing habitat for diverse wildlife. However, there are fewer studies on the genetic management of mangrove plants. In this study, chloroplast genome Hibiscus tiliaceus L. was obtained through whole resequencing. The complete species 161,764 bp length comprised 84 protein-coding genes, eight rRNA (ribosomal RNA) 37 tRNA (transfer genes. We conducted comparative analysis genomes...
The catalytic performance of oxygen evolution reaction (OER) catalysts is influenced by their elemental composition. Aluminum (Al) offers abundant active sites due to its high oxidation affinity, which makes it unstable in both acidic and alkaline environments. We used the gas atomization method (GAM) prepare aluminum-containing single-phase high-entropy alloy AlxCoCrFeNi2.1 (x = 0, 0.1, 0.3, 0.5, 1). Besides, changing aluminum content HEAs can control particle size. GAM enable with...
