CO2‐to‐Cyclic Carbonate Transformation at Ambient Pressure Using a Mechanochemically Prepared Ti(III) Catalyst

open access: yesAdvanced Synthesis &Catalysis, Volume 367, Issue 18, September 29, 2025.
A Ti(III) complex synthesized mechanochemically catalyzes the cycloaddition of CO2 (1 bar) with terminal, internal, and trisubstituted epoxides. Mechanistic studies by density functional theory calculations reveal that the superior activity of Ti(III) compared to Ti(IV) arises from its lower oxophilicity, facilitating CO2 insertion into Ti–O bonds, as ...

The Permo‐Carboniferous Basins of the Catalan Pyrenees (NE Iberia): An Example of Interacting Tectonics and Collapse Calderas

open access: yesTectonics, Volume 44, Issue 7, July 2025.
Abstract The Permo‐Carboniferous terrains of the Catalan Pyrenees show evidence of extensive calc‐alkaline orogenic volcanism with predominant pyroclastic deposits of dacitic to rhyodacitic composition. These Permo‐Carboniferous basins have been interpreted as volcano‐tectonic depressions associated with a transtensional regime following the Variscan ...
