In the scope of the master’s thesis, four unique iridium catalysts for hydrogen isotope exchange were prepared by modifying the phosphine ligand of the Kerr’s type catalyst. Attaching the latter complex to dendrimer supports via an amide linkage was of particular interest. The synthesised iridium species were tested in a model reaction, deuteration of acetophenone. The obtained results were compared to the activity of the commercially available catalyst. It was found that the activity of prepared iridium complexes was comparable to the parent catalyst.
Upon completion of the reaction, recycling of the catalytic species was investigated as well. In a series of NMR experiments, the distribution of functionalised poly(propylene imine) (PPI) dendrimers between organic and aqueous layers was also examined.
