Fulvine is primarily used in research settings as a ligand in organometallic chemistry, particularly in the development of transition metal complexes. Its unique electronic and structural properties make it suitable for stabilizing low-oxidation-state metal centers, which are often involved in catalytic processes. Due to its ability to donate electron density and form stable coordination compounds, fulvine has been explored in the design of catalysts for organic transformations such as hydrogenation, hydroformylation, and C–C bond formation. Additionally, its photochemical behavior has attracted interest in photophysical studies and potential applications in light-responsive materials. However, its use remains largely confined to academic and experimental investigations due to limited commercial availability and stability constraints.
