Desulfurization of Benzothiophene Derivatives by Solvent Extraction Coupled With Oxidation Using Oxomolybdenum(VI) Bis(pyrazolyl)methane Catalysts

European Journal of Inorganic Chemistry, EarlyView.
A polymeric hybrid material formulated as [MoO3(bis(pyrazolyl)methane)] has been prepared and used as a catalyst precursor for the complete oxidative desulfurization of a model diesel containing recalcitrant benzothiophene derivatives. The precursor is converted in situ to an oxodiperoxo active species which is retained in the recyclable extractant ...

Additives Promote Divergent Reactivity in Photolytic Deoxygenation and Lactonization Reactions of Cobalt Alkoxycarbonyls

European Journal of Organic Chemistry, EarlyView.
We report a carbonylation‐homolysis process to access acyl radicals that can undergo decarboxylation or cyclization onto tethered alkenes. In both cases, ligands and additives are shown to influence the outcome to give saturated or unsaturated products, in some cases with isomerization of the initial products.

Synthesis of Sulfur Heterocycles by Palladium‐Catalyzed Cyclization

European Journal of Organic Chemistry, EarlyView.
In spite of the well‐known palladium thiophilicity, sulfur‐containing acyclic substrates may efficiently undergo several different kinds of palladium‐catalyzed cyclization processes leading to highly important sulfur heterocycles in one synthetic step. Advances in this challenging and stimulating field of research are presented in this review.

Recent Advances in Conjugated Microporous Polymers for Photocatalysis: Mechanism, Synthesis and Applications

Exploration, EarlyView.
Conjugated microporous polymers (CMPs) have attracted more and more attention as new photocatalysts due to their unique advantages such as high performance, long stability and strong light absorption. This review summarizes the application of CMPs as a photocatalyst in recent years and introduces the catalytic mechanism.

Indole‐Based π‐Extended Monophosphine Ligands for Enhanced Palladium‐Catalyzed Sonogashira Coupling

Journal of Heterocyclic Chemistry, EarlyView.
A general palladium‐catalyzed Sonogashira cross‐coupling of (hetero)aryl chlorides with aliphatic, (hetero)aryl alkynes is described using Pd(dba)₂/PCy2‐Napdole‐phos catalyst system. The reaction protocol exhibits broad substrate scope and the catalyst loading can be down to 0.2 mol% Pd.

Prevalence of anthelmintic resistance of gastrointestinal nematodes in Lithuanian sheep farms

Helminthologia
The rapid emergence of anthelmintic resistance (AR) among gastrointestinal nematodes (GIN) in Europe, particularly to benzimidazoles (BZ), levamisole (LEV), and macrocyclic lactones (ML), presents a growing challenge to sheep farming. This study aimed to

Sensitivity of Irish Pyrenopeziza brassicae populations to methyl benzimidazole carbamate (MBC), quinone outside inhibitor (QoI) and succinate dehydrogenase inhibitor (SDHI) fungicides

Pest Management Science, EarlyView.
For three collections of Irish Pyrenopeziza brassicae populations fungicide sensitivity status to methyl benzimidazole carbamate (MBC), quinone outside inhibitor (QoI) and succinate dehydrogenase inhibitor (SDHI) fungicides was determined using sensitivity screening in vitro. Molecular mechanisms of insensitivity have been identified for MBC and QoI in

Mechanochemical Fullerene Nanoencapsulation in Amino‐Functionalized ZIF‐12 for Visible‐Light Disinfection of Waterborne Viruses and Bacteria

Small, EarlyView.
A solvent‐minimized mechanochemical strategy enables the synthesis of C₆₀‐encapsulated amino‐functionalized ZIF‐12 as a visible‐light‐driven bifunctional photocatalyst. Synergistic charge separation enhances hydroxyl radical generation, achieving efficient viral in saline water and bacterial inactivation in river water under environmentally relevant ...
