摘要：

The gold(I) precursor Au(O2CNEt2)(PPh3) has been successfully employed to graft isolated Au(PPh3) fragments on amorphous silica. Molecular models of the silica surface. i.e. Ph3SiOH, (c-C5H9)(7)Si7O12SiOH and (c-C5H9)(7)Si7O9(OH)(3), have been found to react with Au(O2CNR2)(PPh3), R = Me, Et, yielding the corresponding silanolato molecular complexes containing the SiO-Au(PPh3) moiety. Gold nanoparticles on silica have been produced by using AuCl(CO) as precursor.
