The Versatility of Diazirines: Properties, Synthetic and Modern Applications
Chemistry – 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 ...

ChemistrySelect, 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 ...

Meteoritics &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 ...

Biotropica, Volume 57, Issue 3, May 2025.Shade houses serve as effective scientific tools for ex situ cultivation and orchid conservation in tropical forests. A comparison of the floral scent chemistry of Cyrtorchis letouzeyi between shade houses and natural populations in Cameroon revealed the same dominant compound, identical qualitative compositions across sites, but variations in emission

Formation of Structurally Bound Carbonate in Silicate Melts on the Top of the Mantle Transition Zone
Geophysical Research Letters, Volume 52, Issue 3, 16 February 2025.Abstract Carbon‐bearing dense silicate melts may account for the seismically weak layers on top of the mantle transition zone (MTZ) at 13–14 GPa. How carbon is incorporated into silicate melts at such high pressures has not been experimentally probed, making the nature of carbon in dense melts elusive.

Chemistry – A European Journal, Volume 31, Issue 4, January 17, 2025.A detailed comparison of σ‐donation indicators, including the calculated 1JC−H coupling constant, across a broad spectrum of diverse carbenes provides new insights into their strengths and limitations. This study highlights the utility of 1JC−H for assessing σ‐donation in structurally similar carbenes, while revealing its constraints for carbenes with ...
