Graphical Abstract

We demonstrate the synergistic approach of in situ generated iridium nanoparticles in photoredox-catalyzed and CH-functionalization hydrogen isotope exchange with deuterium and tritium gas.

Abstract

We have studied the photoredox-catalyzed hydrogen isotope exchange (HIE) reaction with deuterium or tritium gas as isotope sources and in situ formed transition metal nanoparticles as hydrogen atom transfer pre-catalysts. By this means we have found synergistic reactivities applying two different HIE mechanisms, namely photoredox-catalyzed and CH-functionalization HIE leading to the synthesis of highly deuterated complex molecules. Finally, we adopted these findings successfully to tritium chemistry.
