Polysilane‐Supported Nickel as an Efficient Catalyst for the Hydrogenation of Aromatic Compounds†

Chinese Journal of Chemistry, EarlyView.
A Ni/Si catalyst obtained from the reaction of poly(monohydro)silane with Ni(cod)2 serves as an effective heterogeneous catalyst for the hydrogenation of arenes under reaction conditions that are significantly milder than those required for conventional nickel‐based catalysts such as Raney nickel.

Directed Hole Localization Stabilizing Interfacial Sulfur Species to Boost α‐C–H Activation for Selective Biomass Photo‐oxidation

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Efficient α‐C–H bond activation and directional conversion for selective biomass photo‐oxidation are achieved by integrating polarization and interface engineering strategies in P‐doped ZnIn2S4 polar photocatalysts, which leverage hole localization and stable interfacial sulfur species, endowing bio‐based HMF at 94.4% conversion with 94.5% selectivity ...

Push–Pull Ynamines and Push–Pull Ynamides: Synthesis, Structure, Reactivity, and Application

European Journal of Organic Chemistry, EarlyView.
Push–pull ynamines and push–pull ynamides, which carry an EWG and an amino or amido group as EDG, are highly interesting classes of EDG‐EWG alkynes that have been intensively studied due to their exceptional reactivity. In this review, the synthesis, structure, reactivity, and application of push–pull ynamines, push–pull ynecarbamates, push–pull ...

Secondary Brown Carbon Formation From Photooxidation of Furans From Biomass Burning

Geophysical Research Letters
Furans are a major class of volatile organic compounds emitted from biomass burning. Their high reactivity with atmospheric oxidants leads to the formation of secondary organic aerosol (SOA), including secondary brown carbon (BrC) that can affect global ...

Emerging Trends in Organic Photoreactions Utilizing Disulfides

European Journal of Organic Chemistry, EarlyView.
Disulfides are versatile, nontoxic alternatives to metal photocatalysts. This review explores their role as photoactivated thiyl‐radical precursors and bifunctional catalysts (HAT/electron shuttling) in diverse transformations. Strategies for electronic tuning and development into recyclable heterogeneous materials are highlighted for sustainable ...

Gap Analysis of Metabolic Conversions of Off-Flavors and Antinutrients in Plant-Based Substrates. [PDF]

Compr Rev Food Sci Food Saf
ABSTRACT To drastically reduce the carbon footprint of the food production chain, a major shift towards alternatives to conventional meat and dairy products is required. The use of plant‐based proteins is a promising route, but it also comes with challenges: Plant‐based proteins often contain antinutritional factors and off‐flavors, which can ...

Design and Synthesis of Lactose‐Derived Ligands and Their Application in Asymmetric Friedel–Crafts Alkylation

European Journal of Organic Chemistry, EarlyView.
This work describes the synthesis of lactose‐ and glucose‐derived chiral ligands and their application in the catalytic enantioselective Friedel–Crafts alkylation of indole with a series of trans‐β‐nitrostyrenes. The optimal ligand was an acetate protected, lactose‐derived pyridyl imine and its zinc complex afforded ees up to 93% and yields up to 93 ...
