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 ...

Isolable ArInH2: Double Hydroindation Agent

Chemistry – A European Journal, EarlyView.
Stable crystalline monomeric indium dihydride ArInH2 was isolated and completely characterized using effective support of the P,C,P‐pincer ligand (Ar = 2,6‐(tBu2PO)2C6H3). It serves as unparalleled hydroindation agent, thereby extending the family of known hydrometallation process relying on heavy p‐block metals.

GH172 Difructose Dianhydride I Synthase: A Two‐Stepped Journey via Glycosylation and Cyclization Using QM/MM Metadynamics

Chemistry – A European Journal, EarlyView.
Unlocking the chemistry of caramel by simulations and experimental validation. αFFase1${\alpha }\rm{FFase1}$ converts inulobiose into difructose dianhydride I, one component of caramel, through two steps: a rate‐limiting glycosylation (with a rare sugar ring flip) followed by a cyclization step, guided by residues E85, K147, and N226.

Photochemical and Thermal Activation of a Diarylbismuth Azide

Chemistry – A European Journal, EarlyView.
We report the synthesis and characterization of a novel diarylbismuth azide and its divergent reactivity upon thermal or photochemical activation. These findings contribute expanding the reactivity landscape of heavy pnictogen compounds and sets the basis for further investigations. ABSTRACT Azides are widely employed in synthesis as convenient nitrene

Redox‐Switchable Optical and Magnetic Properties in a Self‐Assembled Hexanuclear Ni(II) Double‐Decker Complex

Chemistry – A European Journal, EarlyView.
A triangular double‐decker Ni6 complex self‐assembles from Ni(II), TMEDA, and a triphenylene tris dioxolene non‐innocent ligand, with two face‐to‐face tris‐semiquinone decks held by a strong covalent C─C interaction. This rigid scaffold delivers four reversible ligand‐centered redox events: oxidation switches on an intense near‐infrared band and ...

Si(OTeF5)4 – A Strong, Homoleptic Pentafluoroorthotellurate‐Based Lewis Superacidic Silane

Chemistry – A European Journal, EarlyView.
The homoleptic pentafluoroorthotellurate‐based silane Si(OTeF5)4 was synthesized and fully characterized via spectroscopic techniques. The Lewis superacidic properties were investigated theoretically as well as experimentally and its utilization as a Lewis acid is demonstrated by the reaction with nitrogen bases.

Reduction Process of Pt(IV) Complexes With Axial Acetato Ligands by Ascorbic Acid; Comparison of Experimental and Computational Tools

Chemistry – A European Journal, EarlyView.
Comparison of experimental and calculated rate constants for reduction of selected Pt(IV) complexes by ascorbic acid (AA) in water solution at pH = 7. ABSTRACT In the present work, the reduction mechanism of several Pt(IV) complexes bearing two axial acetato ligands by ascorbic acid (AA) was investigated.
