While the actinide salts because of their Lewis acidity and flexible coordination geometry demonstrate unique possibilities as catalysts, research with actinide catalysts typically involves complexed organoactinide frameworks. Many actinide salts have yet to be explored in catalysis or as reagents in metal mediated synthesis. Here, the synthesis of the heterocycle 2,3-diaminophenazine has been reported in good yields in the presence of oxygen via the first use of thorium nitrate or uranyl nitrate as the catalyst.
