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

open access: yesChemistry – 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 ...

Evaluation of Pervaporation and Nanofiltration Membranes for Water Recovery From Thermo‐Responsive Draw Solution

open access: yesChemie Ingenieur Technik, EarlyView.
Integrating thermo‐responsive draw solutions with suitable water‐recovery technologies could enable more efficient hybrid desalination. This study compares pervaporation and nanofiltration, revealing key trade‐offs between water productivity and polymer retention and providing guidance for future FO‐based brine treatment systems.

Charge State Influence on Stability and Isomerism in Dehydrogenated PAHs: Insights from Anthracene, Acridine, and Phenazine

open access: yesChemPhysChem, Volume 26, Issue 6, March 15, 2025.
The ionization of anthracene, acridine, and phenazine has been explored, along with the removal of one and two hydrogen atoms, to provide valuable information for astrochemists and to understand the behavior of the resulting structures and their electronic reorganization. Abstract In this study, we systematically explored the stability and isomerism of

Risk of Bias Associated with Varying Sampling Strategies for External Comparator Cohorts for Single‐Arm Trials: Insights from Aggressive Lymphoma

open access: yesClinical Pharmacology &Therapeutics, EarlyView.
Marketing authorizations for oncology drugs are often based on single‐arm trials (SATs), and real‐world data‐based external comparator cohorts (ECCs) are increasingly explored to contextualize results. In retrospective studies, comparators may be identified by time of diagnosis but included based on time of relapse; such sampling strategies can ...
