Pd‐Catalyzed Cyclotrimerization and Cycloaddition of 5,6‐Didehydrobenzo[8]annulenes (BenzoCOTynes): Formation of Nonplanar Tri[8]annulenes and Diels–Alder Cycloadducts

open access: yesEuropean Journal of Organic Chemistry, Volume 29, Issue 23, 16 June 2026.
A Pd(0)‐catalyzed cyclotrimerization of benzoCOTynes to form tri(benzo[8]annulenes) was developed. Three distinct isomers were isolated and structurally characterized by single‐crystal X‐ray diffraction. Ligand modulation proved crucial for enhancing regioselectivity: P(4‐OMePh), and (S)‐tBu‐Phox promoted the formation of the symmetric isomers.

Ostinazione urbana

open access: yes, 2023
Tratto distintivo del lavoro di Gino Malacarne è l’ostinata ricerca di chiarezza compositiva. Declinata come una necessità della città, cui il progettista ha la responsabilità di rispondere in modo inderogabile, questa finisce con il collocare ...

Deciphering pH Behavior in Deep Eutectic Solvents: Synergizing Experimental Data and Computational Modeling

open access: yesChemCatChem, Volume 18, Issue 11, 15 June 2026.
Proton activity in deep eutectic solvents (DESs) remains difficult to quantify. Here, pH in hydrophilic and hydrophobic DESs is probed by combining glass electrode measurements with ultraviolet–visible (UV–vis) pH indicators and Gaussian process (GP) machine learning (ML).

[FeFe]‐Hydrogenase Mimics Bearing Germylene Ligands: Synthesis, Protonation, and Electrochemical Properties

open access: yesChemistryEurope, Volume 4, Issue 6, June 2026.
Protonation dynamics and spectroscopic detection of elusive intermediates in [FeFe]‐hydrogenase mimics bearing germylene ligands reveal key roles of ligand basicity in catalytic behavior. This work shows that the presence of germylene ligands of marked basicity in [FeFe]‐hydrogenase mimics of the type [Fe2(µ‐S2X)(E)n(CO)6–n] (S2X = (SCH2)2N(p‐MeOC6H4) (

Orfeo como autor mítico en los manuales hispanos de literatura griega: el lento derribo de un tópico historiográfico

open access: yesMyrtia, 2018
En este trabajo, intentamos buscar las razones por las que Orfeo continúa apareciendo en calidad de poeta mítico en los manuales europeos e hispanos de literatura griega a lo largo del siglo XIX.

(Re)considering Robert Henryson’s Orpheus and Eurydice as a Dream Vision

open access: yesNalans, 2022
This study aims to reconsider the Scottish poet Robert Henryson’s retelling of the myth of Orpheus in his Orpheus and Eurydice (c. 1470) as a late example of medieval dream vision genre. There are two prominent versions of the myth in the medieval world:

Extending the Boundaries With Electron‐Rich Tris(pyridyl)borates in Classical Silver and Gold Carbonyl Complexes

open access: yesChemistryEurope, Volume 4, Issue 5, May 2026.
Electron‐rich tris(pyridyl)borate stabilizes rare silver(I) and gold(I) carbonyl complexes. The resulting Ag–CO and Au–CO species show record‐low CO stretching frequencies, revealing enhanced metal→CO π‐backbonding. Structural and computational analyses highlight strong ligand donation, steric protection, and distinct bonding behaviors between the two ...

The Influence of Fluvial Incision on the Lithospheric Stress Field: A Numerical Approach

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.
Abstract Erosion along large fluvial valleys transports important sedimentary volumes across continents over geological time, modifying the loads imposed on the lithosphere and inducing isostasy‐related subsurface stresses. This work presents numerical experiments with a visco‐plastic lithosphere aimed at understanding the distribution and evolution of

Vicent Blasco Ibáñez: antisemitisme entre tarongers

open access: yesDebats. Revista de cultura, poder i societat, 2018
El discurs de Blasco Ibáñez, en ocasions radical i polèmic, fortament anticlerical, va ser en determinats moments també obertament antisemita. Analitzem les claus de la judeofòbia en Blasco Ibáñez mitjançant l’estudi de l’evolució del prejudici antijueu ...
