Tritiated compounds are invaluable tools for in vitro and in vivo studies on bioactive
molecules. Here we describe a ‘click-chemistry’-based strategy for deuteration and
tritiation of multifunctional compounds and multimodal molecular imaging probes. The
method relies on a palladium-mediated reductive deiodination of 5-iodo-1,2,3-triazoles
in the presence of NaBD4, deuterium or tritium gas.
