Catalytic oxidative C-H bond functionalization reactions that proceed without requiring stoichiometric amounts of external oxidants or pre-functionalized oxidizing reagents could maximize the atom- and step-economy in chemical syntheses. However, such a transformation remains elusive. Here, we report photo-driven catalytic process enables decarboxylative trifluoromethylation (hetero)arenes with trifluoroacetic acid as trifluoromethyl source good yields presence an oxidant far lower than (for...
The photoredox-catalyzed fluoroalkylation of alkynes has been developed with silacarboxylic acid as an easily accessible, safe, and highly stable novel halogen-atom transfer mediator.
CO<sub>2</sub> insertion is facilitated by the critical effects of a Lewis acid and an agostic interaction.
Herein, we report a metal-free intramolecular carbofluorination protocol for the synthesis of tetrasubstituted monofluoroalkenes from internal α,β-ynones and Selectfluor with both high stereoselectivity broad functional group tolerance. The chelation between tetrafluoroborate anion oxygen present in aldehyde rendered reaction highly stereoselective, serving as direct fluorine source. Therefore, addition sodium tetrafluoroborate, could be reused several times without sacrificing reactivity.
An unprecedented palladium-catalyzed and visible-light-driven relay reaction of allenylphosphine oxide with in situ generated nitrile imines is presented for the direct synthesis highly valuable polyarylbipyrazole skeletons. This one-pot strategy involves double 1,3-dipolar cycloaddition C(sp3)–P(V) bond cleavage under photocatalyst-free mild conditions. The approach features simple operation, a high step economy, broad substrate scope, affording corresponding products moderate to excellent yields.
Abstract Base promoted [4+3] annulation of trifluoromethylpyrazole(TFPZ) derived α , β ‐unsaturated ketones with crotonate‐derived sulfur ylides provided a diverse set CF 3 ‐containing oxepino[2,3‐ c ]pyrazole motif in good to excellent yields through simple, mild and fast manner. Significantly, one‐pot strategy could be successfully applied this transformation from available materials. Also, the utility our versatile protocol was further demonstrated by gram‐scale reaction useful derivation.
Abstract Trioctyl hydroxyethyl ammonium chloride was synthesized from trioctylamine, hydrochloric acid and ethylene oxide by a two-step process. The structure of the quaternary salt characterized FTIR 1 H NMR. surface tension at critical micelle concentration measured to investigate activity it.
The development of efficient and stable catalysts with high mass activity is crucial for acidic oxygen evolution reaction (OER). In this study, CeO2-Ir heterojunctions supported on carbon nanotubes (CeO2-Ir/CNTs) are synthesized using a solvothermal method based the heterostructure strategy. CeO2-Ir/CNTs demonstrate remarkable effectiveness as OER, achieving 10.0 mA cm−2 at low overpotential only 262.9 mV maintaining stability over 60.0 h. Notably, despite an Ir dosage 15.3 times lower than...
Abstract An efficient nucleophilic substitution reaction between α-bromo-α-fluoroketones and thiophenols or phenols is reported for the synthesis of α-fluoro-β-ketosulfides α-fluoro-β-ketone ethers in yields ranging from 78–93%. This method exhibits good functional group tolerance a broad scope substrates, including natural phenolic compounds.
A novel palladium-catalyzed cross-coupling of C-H bonds 2-susbtituted indoles with allyltrimethylsilanes coupling partners has been developed. The optimal conditions for the reaction were identified after various examined, which no additional fluoride anion source activated allylsilanes required, using Pd(OAc)2 as catalyst and Cu(OTf)2 oxidant, leading to synthesis benzindoles bearing allyl group in good high yields.
