The Versatility of Diazirines: Properties, Synthetic and Modern Applications

open access: yesChemistry – A European Journal, Volume 31, Issue 43, August 1, 2025.
Diazirines are 3‐membered heterocycles containing two nitrogen atoms connected by a double bond. They possess a multi‐faceted reactivity that holds great potential for organic synthesis. This review discusses their properties, modes of activation, and their many modern uses, underlining their underappreciated versatility: as carbene precursors, but ...

The Halogen Effect in [Cu(NHC)X] Compounds: A Case Study on the Anti‐Leishmania and Antiviral Activity of [Cu(IPr)X]

open access: yesChemistrySelect, Volume 10, Issue 31, August 15, 2025.
This study explores how changing halidesfrom Cl to Iinfluences ionic radius, antioxidant activity, and lipophilicity. These shifts significantly impact the biological potency of [Cu(IPr)X] compounds against Leishmania parasites and arboviruses. A strategic tweak in halogen identity paves the way for enhanced therapeutic performance in metal‐based drug ...

Simulating evaporative wet and dry cycles in Gale crater, Mars using thermochemical modeling techniques

open access: yesMeteoritics &Planetary Science, Volume 60, Issue 8, Page 1704-1720, August 2025.
Abstract The aim of this work is to provide a model‐backed hypothesis for the formation of evaporites—sulfates, borates—in Gale crater using thermochemical modeling to determine constraints on their formation. We test the hypothesis that primary evaporites required multiple wet–dry cycles to form, akin to how evaporite assemblages form on Earth ...
