Bis(2‐Adamantyl)Magnesium: Synthesis, Structure, and Applications of a Versatile and Shelf‐Stable 2‐Adamantyl Anion Equivalent

Chemistry – A European Journal, EarlyView.
At last, the long‐sought bis(2‐adamantyl)magnesium reagent has been prepared in high yield as a stable tetrahydrofuran/dioxane adduct and fully characterized by x‐ray crystallography. This potent nucleophile outperforms the corresponding Grignard in transmetallation and carbonyl addition reactions, opening new avenues in adamantyl organometallic and ...

Synthesis and Photophysical Properties of Star‐Shaped Triphenylamine Trimers Functionalized With BODIPY and Subphthalocyanine Chromophores

Chemistry – A European Journal, EarlyView.
This study investigates how molecular topology influences the photophysical properties of star‐shaped, threefold‐symmetric triphenylamine (TPA) derivatives functionalized with three BODIPY or SubPc units. Their absorption spectra exhibit minimal solvatochromism, whereas their fluorescence intensity is strongly dependent on solvent polarity.

Sustainable Hydrogen Production by Glycerol and Monosaccharides Catalytic Acceptorless Dehydrogenation (AD) in Homogeneous Phase

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
Sustainable hydrogen production can be obtained from hydogen‐rich biomass‐derived organic molecules through Acceptorless Dehydrogenation (AD) reactions. Glycerol and sugars are available in large quantities from industry and can be successfully used as substrates in AD protocols, in the presence of tailored, selective, easily tunable and thermally ...

Understanding Consumption of Illicit Drugs and New Psychoactive Substances in Australia by Triangulating Drug Checking and Wastewater‐Based Epidemiology

Drug Testing and Analysis, EarlyView.
First Australian study combining wastewater‐based epidemiology and drug checking, demonstrating how complementary data sources enhance monitoring of illicit drugs and emerging psychoactive substances during high‐use periods. ABSTRACT Consumption of psychotropic drugs is a major economic and public health challenge in Australia.
