Abstract

The effect of Pd doping on the ligand-exchange reactivity of Au(25)(SC(12)H(25))(18) was studied by comparing the ligand-exchange reactivity of [Au(25)(SC(12)H(25))(18)](-) and [PdAu(24)(SC(12)H(25))(18)](0) and the results clearly demonstrate that, regardless of the kind of incoming thiols and solvents, Pd doping greatly increases the rate of ligand exchange of Au(25)(SC(12)H(25))(18), indicating an enhanced ease of ligand exchange.
