Used as a catalyst precursor in organic synthesis, particularly in transfer hydrogenation and C–H activation reactions. Its unique half-sandwich structure stabilizes reactive intermediates, making it effective in promoting asymmetric transformations. Commonly employed in the reduction of ketones and aldehydes under mild conditions. Also utilized in materials science for depositing ruthenium-containing thin films via chemical vapor deposition. Serves as a starting material for synthesizing other ruthenium-based complexes with tailored reactivity.
