  A series of organosiloxo complexes of platinum and palladium, MR(OSiPh3)(L-2) (M = Pt, Pd; R = Me, Et, Ph; L-2 = cod, dppe), has been prepared and characterized. The square planar geometries of PtPh(OSiPh3)(cod) and PtEt(OSiPh3)(cod) are confirmed by X-ray structure analysis. In the reactions with hydrogen at 0 degrees C and 1 atm, the siloxo complexes of Pt and Pd are reduced readily to give agglomerates of nanoclusters with complete hydrogenation of the ligands. The reduction activities of the siloxo and alkoxo complexes are higher than those of the corresponding alkyl complex PtMed(2)(cod). This high activity in reduction is applied to the preparation of supported Pt or Pd nanoclusters on silica, and the siloxo complexes adsorbed on silica are reacted with hydrogen at mild conditions. The resulting Pt/SiO2 gives a smaller mean diameter than that prepared from H2PtCl6/SiO2. (C) 1999 Elsevier Science S.A. All rights reserved.
