Triruthenium dodecacarbonyl is widely used as a catalyst in various organic synthesis processes, particularly in hydrogenation and hydroformylation reactions. It facilitates the conversion of unsaturated hydrocarbons into saturated compounds, making it valuable in the production of fine chemicals and pharmaceuticals. Additionally, it is employed in the synthesis of complex organic molecules, including natural products and polymers, due to its ability to promote carbon-carbon bond formation. In materials science, it serves as a precursor for the deposition of ruthenium thin films, which are essential in the fabrication of electronic devices and coatings. Its role in catalysis extends to environmental applications, such as the reduction of harmful pollutants in industrial emissions.
