Coupled Photocatalytic Hydrogen Production With Selective Biomass Valorization via Active Sites Construction and Electron Transport Channels Engineering

Carbon Energy, EarlyView.
A ternary CdS/1T‐WS2/CNTs heterojunction is in‐situ constructed via hydrothermal method, which is used for photocatalytic biomass reforming (biomass‐derived alcohols, lignin). It exhibits outstanding performance: H2 production rate of 26.17 mmol/g/h for benzyl alcohol (BA), benzaldehyde (BD) generation rate of 8.29 mmol/g/h, 90.06% BD selectivity, 100%

Synthesis of 3-Aroyl-4-heteroarylpyrrole Derivatives by the Van Leusen Method

Molbank, 2022
The synthesis and structural diversification of N-heterocycles systems have attracted much attention because of their potential applications. Three 6-aryl-3-methyl-1-phenyl-1H-pyrazolo[3,4-b]pyridine-5-carbaldehyde 4 derivatives, in reaction with ...

Oxidative Generation and Reactivity of the Cyclopropyl Radical From a Martin Silicate

Chemistry – A European Journal, EarlyView.
A photoredox strategy employing Martin silicates enables the oxidative generation and controlled capture of cyclopropyl radicals, including the naked one, long considered challenging intermediates. The method affords functionalized cyclopropanes through both Giese‐type additions and dual nickel/photoredox C(sp3)−C(sp2) cross‐couplings.

Electrochemiluminescence of Heteroleptic Iridium(III) Complexes Featuring Substituted 2,4‐diphenylpyridinato Ligands

Chemistry – A European Journal, EarlyView.
Five heteroleptic iridium(III) complexes bearing cyclometalated 2,4‐diphenylpyridinato ligands were synthesized and their electrochemiluminescence (ECL) investigated. Two different coreactants were evaluated: tri‐n‐propylamine and benzoyl peroxide under anodic and cathodic potentials, respectively.

Catalytic Hydrothermal Liquefaction of Polyethylene With Pt/C to Tune Product Selectivity

CleanMat, EarlyView.
Pt/C‐catalyzed hydrothermal liquefaction of polyethylene in supercritical water enables time‐dependent control of product selectivity, producing paraffin‐rich oils at shorter reaction times and aromatic‐enriched products at longer times without external hydrogen. ABSTRACT Hydrothermal liquefaction (HTL) represents a promising thermochemical pathway for

Microwave-Assisted Synthesis of Acetophenone (per-O-acetylated-β-D-glucopyranosyl)thiosemicarbazones

E-Journal of Chemistry, 2010
Thirteen new substituted acetophenone (2,3,4,6-tetra-O-acetyl-β-D-glucopyranosyl)-thiosemicarbazones (3) were synthesized by reaction of 2,3,4,6-tetra-O-acetyl-β-D-glucopyranosyl thiosemicarbazide (1) and substituted acetophenones (2).

(2-Chloroanilino)acetophenone [PDF]

Acta Crystallographica Section E Structure Reports Online, 2005
The title compound, C14H12ClNO, is used in perfumery, as a catalyst for the polymerization of olefins, and in organic synthesis, especially as a photosensitizer and in the manufacture of dyes. The mol­ecule is essentially planar and has a trans configuration. In this configuration, the Cl and O atoms shield the amino H atom, preventing the formation of

Retro‐Hetero‐Michael Addition Strategies in Organic Synthesis

European Journal of Organic Chemistry, EarlyView.
In this review, synthetic approaches to carbo‐ and heterocyclic compounds, including natural products, published in the last 15 years (2011–2025) which have either relied upon or included a retro‐hetero‐Michael addition step at any stage are discussed.

A Cholesterol Analogue for Cell‐Surface Enzyme Display

Angewandte Chemie, Volume 138, Issue 34, 17 August 2026.
We report a non‐genetic strategy for bacterial cell surface enzyme immobilisation using cholesterol‐based artificial lipids containing Ni2+‐NTA binding groups that can integrate into biological membranes. The engineered cells can capture His‐tagged enzymes directly from cell lysates while preserving intracellular and surface activity, allowing for ...
