Photoinduced transition-metal- and photosensitizer-free cross-coupling of aryl halides (including Ar–Cl, Ar–Br, Ar–I) with H-phosphonates dialkyl phosphonates diarylphosphine oxides) is reported. Various functional groups were tolerated, including ester, methoxy, dimethoxy, alkyl, phenyl, trifluoromethyl, heterocyclic compounds. This simple green strategy provides a practical pathway to synthesize arylphosphine oxides.
Bismuth oxyhalides (BiOX) nano-materials are considered to be the most encouraging candidates deal with environmental remediation, energy conversion, and degradation of organic pollutants because their attractive characteristics, such as appropriate band structure, suppressed charges recombination ability, good catalytic activity. The pure BiOX does not justify advisable fine-tune photocatalytic efficiency. Therefore, several morphologies synthesized, atomic layers, ultrathin nano-sheets,...
Abstract The synthesis of 4‐(trifluoromethyl)‐2,3‐dihydrothiazoles from α‐enolic dithioesters and imidoyl sulfoxonium ylides has been achieved under thermal conditions. This transformation is catalyst‐free, additive‐free, operationally simple, it proceeds via a formal insertion alkenyl S−H generated in situ into followed by an intramolecular annulation. approach further expands the synthetic application two versatile sulfur‐containing building blocks fluorinated dithioesters. magnified image
“We report a protocol for photoinduced transition-metal- and external-photocatalyst-free intramolecular heteroaryl/aryl rearrangement reactions of 2-heteroaryl/aryloxybenzaldehydes. The was compatible with variety functionalities.
Quartz crystal microbalance (QCM) has attracted extensive attention in the field of biological analysis and detection because its high sensitivity, fast response, real-time measurement, good operability, low-cost production. However, to detect trace amounts small molecules, such as low-concentration saliva glucose under physiological conditions, is still a major challenge. Herein, surface QCM chip was coated with poly(boric acid)-based hydrogel using UV pressing-assisted polymerization...
Preparation of EGCG–Zn–CS using Microwave Irradiation method with excellent biological activity.
Saliva glucose detection using QCM technology has garnered significant attention of non-invasive blood monitoring. Introducing antifouling materials is a pivotal strategy for addressing the issue indiscriminate protein adsorption in saliva. Nonetheless, equipping surfaces with properties often comes at cost compromising sensitivity tests. To tackle this challenge, we engineered an innovative hydrogel that integrates gold nanoparticles functionalized L-cysteine (Au-Cys). When immobilized on...
A copper-catalyzed tandem arylation-cyclization process to access 1-(arylthio)isoquinolines from isothiocyanates and diaryliodonium salts is described. It the first general method construct potentially useful 1-(arylthio)isoquinoline derivatives. Moreover, 1-(methylthio)isoquinoline derivatives were also achieved successfully with MeOTf instead of under metal-free conditions. Mechanistic studies reveal that these two processes proceed in different routes. This has been applied synthesis...
A novel Mn(II)-promoted tandem phosphorylation/cyclization reaction of 2-biaryl isothiocyanates with phosphine oxides is described. This the first general method to synthesize 6-phosporylated phenanthridines from isothiocyanates. The approach featured by oxidant-free, low loading P-reagent, easy operation, and high functional group tolerance.
