of C–H bonds in drugs and the relative ease and low cost associated with tritium (3H) make it an ideal radioisotope with which to conduct ADME studies early in the drug development process. Here we describe an iron-catalysed method for the direct 3H labelling of pharmaceuticals by hydrogenisotopeexchange, using tritiumgas as the source of the radioisotope.

A method for producing a compound having a deuterated aromatic ring or heterocyclic ring according to the invention includes heating a compound having an aromatic ring or heterocyclic ring in the presence of heavy water, a transition metal and a metal which generates deuterium. As the metal which generates deuterium, at least one metal selected from the group consisting of aluminum, magnesium, zinc, iron, lead and tin is preferred. As the transition metal, at least one metal selected from the group consisting of platinum, palladium, ruthenium and rhodium is preferred. The heating is preferably carried out by microwave irradiation.

Both substituted imidazoles and 1,3-dialkylimidazolium salts
can be fully deuteriated on the heterocyclic ring using D2O over
heterogeneous Pd catalysts: deuteriated 1-alkyl-3-methylimidazolium
chloride and hexafluorophosphate ionic liquids can also be prepared in good
yields utilising readily available and relatively low cost sources of
deuterium.

pincer complexes have played an important role in homogeneous catalysis during the last ten years. Yet, despite intense research efforts, the synthesis of iron PCcarbeneP pincer complexes has so far remained elusive. Here we report the synthesis of the first PCNHCP functionalized iron complex [(PCNHCP)FeCl2] (1) and the reactivity of the corresponding trans-dihydride iron(II) dinitrogencomplex [(PCNHCP)Fe(H)2N2)]
