Direct catalytic H/T exchange can be achieved by application of homogeneous or heterogeneous catalysts in presence of tritium gas. The most popular homogenous catalyst is [Ir(cod)(PCy3)(py)]PF6, a commercially available compound also known as Crabtree’s catalyst. It mainly promotes H/T exchange in aromatic ortho-positions of directing functional groups.
