ChemSusChem, EarlyView.Post‐HER surface restructuring of nickel Sulfides (NixSy) through Sulfur leaching results in the formation of catalytically active Ni3S2, the most HER‐active nickel sulphide phase. The electrochemical activation process enhances hydrogen evolution performance while exhibiting self‐limiting behavior, ensuring long‐term catalyst stability in alkaline ...

Helvetica Chimica Acta, EarlyView.Four stereogenic centers are formed diastereoselectively in one step from a cyclic (E,E)‐1,5‐diene system using an electrophilic addition reaction. Subsequent ozonolytic cleavage of the intact Z‐double bond, followed by intramolecular nucleophilic substitution, yields an octahydroterfurandione with a threo,cis,threo configuration, an arrangement found ...

Intensification of diesel oxidative desulfurization via hydrodynamic cavitation
Ultrasonics Sonochemistry, 2019 A Hydrodynamic Cavitation Assisted Oxidative Desulfurization (HCAOD) process was applied for treatment of diesel fuel feedstock using hydrogen peroxide and formic acid as the oxidant and catalyst, respectively. Investigation on the effect of main process variables including pressure drop (3-6 bar), time of treatment (10-30 min) and formic acid to ...

Sulfur Ylides in Skeletal‐Editing—Ring Expansion Reactions
Helvetica Chimica Acta, EarlyView.Sulfur ylides (S‐ylides) are emergent diazo surrogates that enable skeletal editing and ring expansion with safer handling and broad functional group tolerance. This perspective covers pioneer works and highlights recent advances in the field, while outlining key challenges and future directions that may redefine the role of S‐ylides in modern ...
