Tris(2-thienyl)phosphine（Cat No.:L045014）is an organophosphorus compound featuring three 2-thienyl (thiophene) groups bonded to a central phosphorus atom. It is commonly used as a ligand in coordination and organometallic chemistry, particularly in catalytic applications such as cross-coupling and polymerization reactions. The electron-rich thiophene rings enhance the ligand’s π-donating ability, influencing the electronic environment of metal centers and improving catalytic activity and selectivity. Its aromatic sulfur-containing structure also contributes to thermal stability and solubility in organic solvents. This compound is valuable in designing advanced catalysts and functional materials in synthetic chemistry.
