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

open access: yesChemSusChem, 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 ...

1,3‐Bis(tetrylene)s: Emerging Platforms for Functional Main‐Group Molecules

open access: yesEuropean Journal of Inorganic Chemistry, EarlyView.
Bridge design governs the stability and reactivity of 1,3‐bis(tetrylene)s. This review surveys pnictogen‐, chalcogen‐, and tetrel‐bridged systems and shows how geometric preorganization and electronic communication can enable cooperative bond activation and access to unusual heavy‐element π frameworks. Main‐group chemistry has undergone a resurgence as

Ligand Redox Noninnocence in Bis(phosphinimine) Diarylamido Pincer Complexes of Nickel

open access: yesEuropean Journal of Inorganic Chemistry, EarlyView.
The oxidative noninnocence of a bis(phosphinimine) ligand featuring a diarylamido backbone was investigated for several nickel complexes. Radical/charge delocalization across the aromatic backbone plays an important role in the stabilization of the diarylaminyl and putative diarylnitrenium complexes.

π‐Extended Silyl Enolates as Emerging Platforms in Radical Chemistry

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
This review covers the emerging role of π‐extended silyl polyenol ethers in radical chemistry. It highlights their versatile roles as electron‐rich SOMOphiles, silyl radical cation precursors, and nucleophilic partners in radical–polar crossover manifolds, while considering recent advances in photoredox catalysis, electrochemistry, and transition metal‐

Tailoring High‐Valent Iron‐Oxo Species Redox via Extended π‐Fe3d–O2p Orbital Overlapping Toward Chemical‐Efficient Water Purification

open access: yesAngewandte Chemie, Volume 138, Issue 38, 14 September 2026.
We address the long‐standing challenge of reactivity–selectivity trade‐off by precisely tuning the redox properties of Fe(IV), rather than simply accelerating its formation, to enable chemically efficient and low‐emission water treatment. ABSTRACT High‐valent iron oxo species (Fe(IV)) are attractive for wastewater treatment because of their high ...
