  Water-Soluble Palladium and Gold Nanoparticles Functionalized by a New Phosphine with Zwitterionic Liquid Based on Imidazolium Sulfonate Linked Ethylene Glycol Moiety

  摘要：

  A new phosphine with zwitterionic liquid based on imidazolium sulfonate linked ethylene glycol moiety (1) as a protective ligand for metal nanoparticles has been prepared. Its phosphine 1-stabilized palladium and gold nanoparticles (1-Pd and 1-Au) were found to be soluble in water, and remarkably stable in high concentration of aqueous electrolyte and ionic liquid. 1-Pd nanoparticles behave as an efficient catalyst for the Suzuki cross-coupling reaction in an aqueous medium.
