Sequence Control in Sulfur‐Containing Ring‐Opening Co‐ and Terpolymerisations

Angewandte Chemie International Edition, Accepted Article.
Sulfur‐containing polymers uniquely expand the catalogue of accessible material properties compared to current commodity materials, yet their synthesis remains underdeveloped. Combining sulfur‐ and oxygen‐containing monomers in ring‐opening copolymerisation leads to a reshuffling reaction of the sulfur centres, which has been challenging to control — a

Diverging Reactivity in Anilidophosphine Supported Group III Complexes

Chemistry – An Asian Journal, EarlyView.
The coordination chemistry and reactivity of anilidophosphine‐supported scandium and yttrium complexes is reported and compared to their lanthanum analogues previously reported by us. The manuscript shows striking differences in the stability and affinity of the anilidophosphine ligand toward these lighter group III metals, resulting in divergent ...

A Versatile Carbonylative Approach to Ureas and Carbamates through Light Activated Nickel Catalyzed Formation of Aliphatic Isocyanates

Angewandte Chemie, Volume 137, Issue 17, April 17, 2025.
A versatile carbonylative approach to prepare aliphatic ureas and carbamates has been developed. The reaction functions with an earth abundant nickel catalyst to generate electrophilic isocyanates from C(sp3) halides, azide and carbon monoxide.

Pyrazine‐Functionalized Ru(II)‐Complexes as Visible‐Light Activated Photobases

Chemistry – A European Journal, EarlyView.
Visible light excitation leads to the accumulation of electron density in pyrazine‐containing Ru(II) complexes via metal‐to‐ligand charge transfer (MLCT). In aqueous solutions of appropriate pH, excited‐state proton transfer (ESPT) takes place on a timescale of hundreds of ps.

On the Facile Synthesis of Triazaarsoles Using Acyclic Precursors

Chemistry – A European Journal, EarlyView.
Easily accessible dichloroarsanes are suitable precursors for the synthesis of novel triazaarsoles, the arsenic analogues of tetrazoles and triazaphospholes. Our findings pave the way to access and fully investigate such aromatic arsenic heterocycles in detail.

Urea Complete Conversion to Compound Fertilizer in Industrial‐Scale Tandem Reactors

Angewandte Chemie, Volume 137, Issue 16, April 11, 2025.
An industrial‐grade tandem system was developed to fully convert urea (or urea wastewater) into compound fertilizer while generating H2. In a typical cycle, 200 g of urea was used to produce 232 L of pure H2 and 1580 g of solid compound fertilizer (KH2PO4 and NH4H2PO4) without further separation. The core is to develop an electrocatalyst (S‐NiOOH‐Ni(OH)

Anthraquinone Sulfonates as Water‐Soluble Photocatalysts: Synthetic Applications and Perspectives

ChemPhotoChem, EarlyView.
The development of photochemistry in water is rapidly advancing, and the demand for water‐soluble photocatalysts is increasing. Accordingly, anthraquinone sulfonates are interesting options for the activation of organic molecules through H‐atom transfer, proton‐coupled electron transfer, or the generation of reactive oxygen species.

Transition Metal‐Free Direct Electrochemical Carboxylation of Organic Halides Using a Sacrificial Magnesium Anode: Straightforward Synthesis of Carboxylic Acids

ChemistryOpen, EarlyView.
The direct electrochemical carboxylation of organic halides was carried out in an undivided cell fitted with a sacrificial magnesium anode and a nickel foam cathode. Mechanism investigations account for the in situ generation of an anionic species that is not a genuine Grignard reagent.

Unveiling aluminum diethyl phosphinate dual identity: Transfer from epoxy resins to glass fiber‐reinforced composites

Polymer Composites, EarlyView.
Comparing resins with composites, different particle sizes of the flame retardant, and the impact of the flame retardant modes of action on different fire properties. Abstract This study examines the transfer of the flame‐retardant aluminum diethyl phosphinate (AlPi) from epoxy resins to composites and the impact of AlPi on fire behavior and fire ...
