Cyclopentadienylbis(triphenylphosphine)ruthenium chloride(CAT: R021648) is a versatile organometallic complex featuring a ruthenium center coordinated to a cyclopentadienyl (Cp) ligand, two triphenylphosphine ligands, and a chloride ion. This compound exhibits exceptional stability and reactivity, making it valuable in homogeneous catalysis and organometallic synthesis. It is widely used in catalytic transformations such as hydrogenation, C–C bond formation, and transfer hydrogenation reactions. The bulky triphenylphosphine groups provide tunable electronic and steric effects, while the Cp ligand offers strong π-backbonding, enhancing complex stability. This ruthenium complex is also investigated in the development of advanced catalysts for fine chemical, pharmaceutical, and materials applications.
