Double Reduction of Ph3B to a Dianionic Borane With a Powerful SrI Intermediate

open access: yesAngewandte Chemie, EarlyView.
Although dianionic boranes follow the octet rule and are isoelectronic to carbanions or amines, the high electron density combined with the electropositive nature of the B center make them highly unstable species. In this study, we present synthesis and full characterization of a complex in which Ph3B2− is sandwiched between two Sr2+ ions and describe ...

An Alkali Amide Approach to Triphosphabenzenes

open access: yesAngewandte Chemie, EarlyView.
Alkali metal amides offer a simple route to phosphorus aromatics. LiNMe2 catalyzes [2+2+2] cyclotrimerization of a phosphaalkyne, while tetrahydrofuran (THF) stabilizes a λ4‐triphosphabenzene anion intermediate. Using KN(SiMe3)2 switches reactivity to arene C(sp3)─H activation, giving benzylated λ4‐triphosphabenzenes and rare λ5‐triphosphabenzenes ...

Concise and Modular Access to a Chiral Biaryl Monophosphine Library and Downstream Use in Catalytic Enantioselective Transformations

open access: yesAngewandte Chemie, EarlyView.
A unified three‐step strategy for a high‐diversity chiral air‐stable biaryl monophosphine library is presented. An atroposelective CpxIrIII‐catalyzed C─H arylation followed by phosphine oxide reduction provides the biaryl ligand building blocks with three different diversity points.

Structural Evolution and Oxygen Evolution Performance of NiFe‐Based Electrocatalysts in Phosphate‐Containing Electrolytes at Non‐Extreme pH

open access: yesAngewandte Chemie, EarlyView.
Phosphate acts as a selective interfacial probe of nickel–iron oxide oxygen evolution electrocatalysts at non‐extreme pH. It reversibly suppresses Ni‐centered oxidation and activity, whereas cycling through the Ni reduction region promotes irreversible catalyst loss.

Interfacial Water‐Networks Regulate the Anodic Stability of Carbon Electrodes

open access: yesAngewandte Chemie, EarlyView.
The hydrogen‐bonding networks of interfacial water serve as active stability descriptors for carbon anodes: disrupted water‐networks accelerate anodic carbon corrosion, whereas strongly hydrogen‐bonded networks suppress it. This principle enables extension of the stable potential window of carbon electrodes through ionomer‐defined interfaces, as ...
