Ligands are the most commonly used means to control regioselectivity of organic reactions. It is very important develop new regioselective methods for synthesis. In this study, we designed and synthesized a single-atomic-site catalyst (SAC), namely, Cu1-TiC, with strong electronic metal–support interaction (EMSI) effects by studying various reaction mechanisms. π cloud back-donation alkyne on metal catalytic intermediate was enhanced during using transient electron-rich characteristics. way,...
Transition-metal-catalyzed carbene insertion reactions of a nitrogen–hydrogen bond have emerged as robust and versatile methods for the construction C–N bonds. While significant progress homogeneous catalytic metal N–H insertions has been achieved, control chemoselectivity in field remains challenging due to high electrophilicity intermediates. Herein, we present an efficient strategy synthesis rhodium single-atom-site catalyst (Rh-SA) that incorporates Rh atom surrounded by three nitrogen...
The semiconducting properties and applications of three dimensional (3D) covalent organic frameworks (COFs) are greatly hampered because their long-ranged non-conjugated skeletons relatively unstable linkages. Here, a robust imidazole-linked fully conjugated 3D framework (BUCT-COF-7) is synthesized through the one-pot multicomponent Debus-Radziszewski reaction saddle-shaped aldehyde-substituted cyclooctatetrathiophene, pyrene-4,5,9,10-tetraone, ammonium acetate. BUCT-COF-7, as metal-free...
The microscopic reaction pathway plays a crucial role in determining the electrochemical performance. However, artificially manipulating still faces considerable challenges. In this study, we focus on classical acidic water oxidation based RuO
A heterogeneous iridium single-atom site catalyst (Ir-SA) was synthesized and investigated in catalyzing the carbene insertion reaction with challenging α-alkyl diazo ester substrates. With only 0.23 mol % loading, our Ir-SA demonstrated remarkable performance N–H bond reactions involving various (hetero) aryl amines coupled esters. Notably, case of using a chiral diamino substrate two reactive sites, exhibited high selectivity toward single insertion, leading to generation class unsymmetric...
Expect the upexpected: A transition-metal-free approach to access chromone derivatives has been developed. The intramolecular O-arylation of substituted 1-(2-haloaryl)-propane-1,3-diones in DMF presence K2CO3 gave corresponding target products good excellent yields (see scheme; DMF=N,N′-dimethylformamide). Detailed facts importance specialist readers are published as "Supporting Information". Such documents peer-reviewed, but not copy-edited or typeset. They made available submitted by...
Regioselective hydroboration of terminal and internal alkynes is realized by using 10 mol% copper powder (0.3-1 μm) at room temperature. 24 were efficiently converted into vinylboronates in up to 96% yield without addition any ligand or additive.
The development of high activity electrocatalysts that can operate stably at current density for the large-scale production hydrogen is an important but challenging task.
Phenol-derived electrophiles are favorable substrates because phenols naturally abundant or can be readily prepared from other aromatic compounds. However, the cleavage of C–O bonds is a great challenge their high energy. K2CO3-catalyzed intramolecular cyclization 1-(2-alkoxyphenyl)-3-akylpropane-1,3-dione and 3-(alkylimino)-1-(2-methoxyphenyl)-2-methylpropan-1-one derivatives via selective reported. The corresponding chromone 4-quinolone were obtained in reasonable yields.
Abstract The property expansion of 3D functionalized covalent organic frameworks (COFs) is important for developing their potential applications. Herein, the first case hydrazone‐decorated COFs as pH‐triggered molecular switches reported, and application in stimuli‐responsive drug delivery system explored. These with hydrazone groups on channel walls are obtained via a multi‐component bottom–up synthesis strategy. They exhibit reversible E / Z isomerization at various pH values, confirmed by...

A novel sodium-promoted Fe-Co/NC catalyst prepared by incipient-wet-impregnation method using ZIF-67 as a support was employed to convert CO2 light olefins through hydrogenation reaction. Properties of the synthesized catalysts calcinated at various temperatures (from 400 700 °C) were investigated XRD, SEM, TEM and Mӧssbauer spectroscopy. Characterization results showed that could be fully converted into carbon above 500 °C, which anchor metal particles, thus resulting in uniform dispersion...
