Dual Nickel/Titanium Catalyzed Cross‐Electrophile Coupling of Thioesters with Benzylic Alcohols

open access: yesChemCatChem, EarlyView.
A nickel‐catalyzed and Lewis acid‐assisted cross‐electrophile coupling between thioesters and electron‐rich benzylic alcohols is described. A series of investigations delivers insights into the mechanism of this transformation. While the thioester is most likely activated through oxidative addition to Ni(0), the alcohol is converted to the ...

Optimization of Active Sites in TiO2–Cu Photocatalysts for H2 Generation via Cellulose Photo‐Reforming

open access: yesChemCatChem, EarlyView.
Three series of titania–Cu photocatalysts have been prepared and tested for hydrogen generation by cellulose photo‐reforming. Copper was incorporated, by impregnation, in P25 (a) and in hydrothermally synthesized TiO2 (b), and also by a one‐pot hydrothermal synthesis (c).

Consequences on Acidity and Reactivity of Inhomogeneous Sodium Exchange in the Shaping of ZSM‐5 with Silica Binders

open access: yesChemCatChem, EarlyView.
The shaping of proton exchanged ZSM‐5 zeolites with silica is shown to strongly impact the properties of the samples, with strong variations depending on the silica source. The Brønsted acidity is measured thanks to pyridine thermodesorption monitored by FTIR and the catalytic activity in m‐xylene isomerization is quantified, which leads to an ...

Experimental and Modeling of Sulfonation of Styrene‐Based Resins Crosslinked With DVB and TMPTA

open access: yesChemical Engineering &Technology, EarlyView.
This study explores how reaction conditions influence the performance of sulfonated styrene resins cross‐linked with DVB and TMPTA. Results show that tuning parameters like temperature and solvent swelling significantly enhances sulfonic group incorporation, especially in TMPTA‐based resins. Modeling reveals key structural differences and insights into
