Synthesis of Sulfur Enriched Cyclohexenes via the Tungsten‐Promoted Dearomatization of a Phenyl Sulfone

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
A method for synthesizing sulfur‐substituted cyclohexenes is reportedthat leverages the η2‐coordination of a phenyl sulfone to [WTp(NO)(PMe3)] (Tp = trispyrazolylborate). Three sequential protonation and nucleophilic additions to the bound arene, followed by oxidative decomplexation, affords functionalized cyclohexenes bearing sp3‐ and sulfur‐enriched ...

Vanillin production from lignin depolymerization by acidic deep eutectic solvent and its possible mechanism

open access: yesEnvironmental Progress &Sustainable Energy, EarlyView.
Abstract As one of the most abundant renewable resources and complex aromatic polymers, lignin holds great promise for producing monophenolic compounds. However, its depolymerization into valuable monomers is hindered by intricate side reactions. In this study, alkaline lignin was converted into vanillin using nine choline chloride‐based deep eutectic ...

Sunlight‐Driven Fixation of CO2 to Cyclic Carbonates Using Carbon Dots as a Photothermal Catalyst

open access: yesExploration, EarlyView.
The first example using carbon dots (CDs) for coupling CO2 with epoxides to generate cyclic carbonates in a metal‐, additive, solvent‐ and electricity input‐free manner under sunlight via photothermal catalytic route is developed. The CDs exhibit highly efficient solar‐to‐thermal conversion with an efficiency of 54%, providing thermal energy for ...

Chitosan‐Based pH‐Responsive Films and Edible Coatings to Enhance Fruit Shelf‐Life: Impact of Plant Biomolecules and Composition

open access: yesFood Chemistry International, EarlyView.
Chitosan based coatings/films forming solution with the use ofplant extracts and parameters for fruit shelf life analysis. ABSTRACT Fresh fruits are a natural source of various minerals and vitamins, which are essential for human health. However, a rapid rate of respiration, water loss and fast ripening ability result in shorter shelf life and ...

Hypolipidemic and Antioxidant Activities of Leptadenia hastata (Perse) Decne. Leaf and Syzygium aromaticum L. Bud Combination: In Vivo, In Vitro, and In Silico Evaluation

open access: yesFood Chemistry International, EarlyView.
Combination of the Leptadenia hastata leaf and the Syzygium aromaticum bud demonstrated hypolipidemic and antioxidant activities in a hyperlipidemic rat model. Combination of the two plants inhibited HMG‐CoA reductase activity, and the docking analysis revealed interacted well and formed binding complexes within the binding pocket of the enzyme ...

Selective Catalytic Oxidation of Benzyl Alcohol to Benzaldehyde With Alkyl Allyl Carbonates and Pd(II) Allyl‐Amidinate

open access: yesHelvetica Chimica Acta, EarlyView.
A Pd(II) allyl‐amidinate complex catalyzes the selective oxidation of benzyl alcohols to aldehydes using allyl alkyl carbonates as tailored, mild oxidants. The carbonate reagent acts both as oxidant and in situ base, enabling chemoselective conversion and minimizing overoxidation under mild conditions.
