Photoredox/Copper Synergistic Catalysis: One-Step Modular Assembly of Sulfonimidamides from Aryl Diazonium Salts, Tr-NSO, and Amines

This paper reports the first photoredox/copper dual-catalyzed, redox-neutral one-step assembly of arylsulfonimidamides from aryl diazonium salts, Tr-NSO, and amines via concurrent C–S and S–N bond formation, offering a highly efficient and general strategy that circumvents competing side reactions and unlocks the reactivity of sulfonimidoyl radicals for constructing diverse S(VI)-containing scaffolds.

PdSn Bimetallic Catalysts Prepared by Electroless Deposition for Enhanced n-Butane Dehydrogenation to Butenes

This study demonstrates that PdSn bimetallic catalysts synthesized via cyclic electroless deposition on surfactant-modified supports exhibit superior n-butane dehydrogenation performance compared to monometallic Pd, with the PdSn/Silica variant achieving optimal conversion and butene yields at 550°C due to enhanced metal dispersion and synergistic Pd–Sn interactions.
