As alcohols are ubiquitous throughout chemical science, this functional group represents a highly attractive starting material for forging new C–C bonds. Here, we demonstrate that the combination of anodic preparation alkoxy triphenylphosphonium ion and nickel-catalyzed cathodic reductive cross-coupling provides an efficient method to construct C(sp2)–C(sp3) bonds, in which free aryl bromides—both readily available chemicals—can be directly used as coupling partners. This paired electrolysis...
Abstract Carbonaceous solid (CS) catalysts with SO 3 H, COOH, and phenolic OH groups were prepared by incomplete hydrothermal carbonization of cellulose followed either sulfonation H 2 SO 4 to give carbonaceous sulfonated (CSS) material or both chemical activation KOH activated (a ‐ CSS) material. The obtained carbon products (CS, CSS, a amorphous; the CSS had small surface area (<0.5 m g −1 ) high group concentration (0.953 mmol ), whereas large (514 low (0.172 ). materials evaluated...
Microcrystalline cellulose could be effectively converted into levulinic acid in pure water at 180 °C 12 h without additives a maximum yield of 51.5% with cellulase-mimetic solid catalyst prepared the use sulfuric acid. Ball-milling pretreatment improved yields by only few percent, showing that binding sites (−Cl) and catalytic (−SO3H) are key to activity catalyst. The spent regenerated H2O2 solution after recycling for 5 times maintain more than 95% its activity. Glucose used as starting...
An extraordinarily simple and highly-efficient chemocatalytic system for production of lactic acid (95.4% yield) from glucose at room temperature ambient pressure is reported.
Functional carbonaceous material (FCM) loaded with carboxylic groups was prepared by hydrothermal carbonization of cellulose in the presence acrylic acid. The resulting FCM used as adsorbent for recovery a water-soluble ionic liquid, 1-butyl-3-methyl-imidazolium chloride ([BMIM][Cl]). consisted microspheres (100-150 nm) and had low surface area (ca. 20 m(2)/g), but exhibited adsorption capacity comparable to that commercial activated carbon which can be attributed high content polar...
An efficient process was developed for the dehydration of fructose to 5-hydroxymethylfurfural (5-HMF) in ionic liquid (IL) 1-butyl-3-methyl imidazolium chloride ([BMIM][Cl]) by using sulfated zirconia as catalyst. A conversion 95.8% with a 5-HMF yield 88.4% achieved 30 min reaction time at 100 °C. The IL and could be recycled exhibited constant activity 6 successive trials, yields above 60% kept up 10 trials. proposed an solid catalyst greatly reduces temperature required over previous works...
Daphnezomines A and B are structurally unusual Daphniphyllum alkaloids that contain a unique aza-adamantane core skeleton. Herein, modular approach to these is presented exploits diverse array of reaction strategies. Commencing from chiral pool terpene–(S)-carvone, the azabicyclo[3.3.1]nonane backbone, which occurs widely in alkaloids, was easily accessed through Sharpless allylic amination palladium-catalyzed oxidative cyclization. protecting group enabled stereoselective B-alkyl...
Canonical nucleosides are vulnerable to enzymatic and chemical degradation, yet their stable mimics-C-aryl nucleosides-have demonstrated potential utility in medicinal chemistry, biology, synthetic although current methods remain limited terms of scope selectivity. Herein, we report a cross-electrophile coupling prepare C-aryl nucleoside analogues from readily available furanosyl acetates aryl iodides. This nickel-catalyzed modular approach is characterized by mild reaction conditions, broad...
Abstract 2D semiconductors, especially transition metal dichalcogenides (TMDCs), have attracted ever‐growing attention toward extending Moore's law beyond silicon. Metal–organic chemical vapor deposition (MOCVD) has been widely considered as a scalable technique to achieve wafer‐scale TMDC films for applications. However, current MOCVD process usually suffers from small domain size with only hundreds of nanometers, in which dense grain boundary defects degrade the crystalline quality films....
Sustainable biomass-derived carbon materials were produced by hydrothermal carbonization of corn stover that was followed chemical activation with KOH. The prepared used for CO2 adsorption and had a uptake 7.14 mmol/g at pressure 1 bar 0°C much higher than activated from direct (2.78 mmol/g). porous stover-derived carbonaceous material high surface area (2442 m2/g) large pore volume (1.55 cm3/g). Product yields obtained the hydrothermally carbonized significantly those (36–75 vs. 8%). CO2/N2...
Uncontrolled inflammatory response highlights the central theme of nonalcoholic steatohepatitis (NASH), a growing global pandemic. Hepatocytes and macrophages represent two major sources hepatic inflammation during NASH pathogenesis, contributing to excessive synthesis proinflammatory mediators. The epigenetic mechanism that accounts for activation hepatocytes in this process remains obscure. Here, we report compared wild‐type littermates, mice with deficiency histone H3K9 methyltransferase...
Despite several methodologies established for C(sp2 )-I selective )-C(sp3 ) bond formations, achieving arene-flanked quaternary carbons by cross-coupling of tertiary alkyl precursors with bromo(iodo)arenes in a manner is rare. Here we report general Ni-catalyzed cross-electrophile coupling (XEC) reaction, which, beyond 3° bromides (for constructing carbons), 2° and 1° are also demonstrated to be viable partners. Moreover, this mild XEC displays excellent selectivity functional group...
