Palladium catalytic system for inhibition of O-arylation type reaction and regioselective direct arylation at C2 of phenols

open access: yes, 2011
International audienceThe palladium-catalysed arylation of free OH phenol derivatives proceeds regioselectively either at C2 or at OH with a variety of electron-deficient aryl bromides or heteroaryl bromides.

Use of Polycyclic Aromatic Compounds as Electrophotocatalysts in Organic Reactions

open access: yesChemistry–Methods, Volume 6, Issue 11, November 2026.
Emerging from the convergence of photoredox catalysis and electrochemistry, electrophotocatalysis is a relatively new and promising synthetic approach in organic chemistry. In this review, the main advantages and the current challenges of this methodology are discussed, while most relevant and late applications of polycyclic aromatic hydrocarbons (PAHs)

Nitrogen‐Doped Mesoporous Carbon Loaded With Zn Single Atoms as a Catalyst for the Synthesis of 2,4(5)‐Diarylimidazoles

open access: yesChemistryOpen, Volume 15, Issue 11, November 2026.
A zinc single‐atom catalyst anchored on nitrogen‐doped mesoporous carbon (Zn@NMC) was synthesized via an evaporation‐induced self‐assembly method and applied in the one‐pot synthesis of 2,4(5)‐diarylimidazoles. The catalyst was fully characterized using FT‐IR, XRD, SEM, EDX, BET, and TGA analyses.

Riluzole‐Derived Benzo[d]thiazoles as CK1δ Inhibitors for Amyotrophic Lateral Sclerosis‐Related Neurodegeneration

open access: yesChemMedChem, Volume 21, Issue 20, 28 October 2026.
Riluzole metabolism guided the design of benzo[d]thiazole inhibitors of casein kinase 1 delta (CK1δ), a kinase linked to amyotrophic lateral sclerosis (ALS). Docking supported ATP site recognition by the hydroxylamine metabolite and hydrazine analogues, leading to compounds showing improved potency and retained predicted blood brain barrier ...

Challenges and Perspectives for an Extended Use of the Dye‐Sensitized Solar Cells

open access: yesSolar RRL, Volume 10, Issue 20, 28 October 2026.
DSSC is a photoelectrochemical technology that will support the energy transition. DSSCs initiated the building‐integrated photovoltaics sector and are now proposed in agrivoltaics, archaeophotovoltaics and as indoor solution for powering the Internet of Things. The wavelength selectivity for photoconversion renders DSSCs unique in photovoltaics ambit.

Synthesis of Tris(indol‐3‐yl)methanes From Indoles, CO2, and Dimethylphenylsilane With BPh3: Two‐Step Construction of π‐Conjugated Systems

open access: yesChemistry – A European Journal, Volume 32, Issue 40, 27 October 2026.
Tris(indol‐3‐yl)methanes were synthesized from indoles, CO2, and PhMe2SiH in the presence of BPh3 in acetonitrile at 50°C. One product, tris(4‐bromo‐1‐methylindol‐3‐yl)methane, underwent a palladium‐catalyzed cascade reaction for the formation of a novel polycyclic heteroaromatic compound, where the methine C(sp3) atom originating from CO2 was ...
