International Journal of Chemical Kinetics, Volume 58, Issue 10, Page 881-889, October 2026.ABSTRACT In the interstellar medium, chemical reactions proceed under conditions vastly different to those on Earth; these include extremely low temperatures and densities and take place in the gas phase and on water–ice grains. Understanding the energetics and more importantly the kinetics of such reactions is of relevance to the consequences on how ...

Asian Journal of Organic Chemistry, Volume 15, Issue 8, August 2026.We report a visible‐light photoredox‐catalyzed strategy for the divergent dual selenylation of inert C─H and N─H bonds. Using a single catalytic system with Ru(bpy)3Cl2·6H2O and diselenides, arylamines and indoles are selectively converted to distinct N,C‐ or C,C‐disubstituted organoselenides, respectively. ABSTRACT We report a visible‐light photoredox‐
