Abstract
Pentamethyldisilane reacts with the dodecacarbonyls of ruthenium and osmium to give the polynuclear complexes [Me3SiM′(CO)3(µ-SiMe2)]2(M′= Ru or Os). These same compounds also arise from the reactions of (Me3Si)2M′(CO)4 with Me5Si2H; however, they are obtained in best yield from [Me3MM′(CO)4]2(M = Si or Ge; M′= Ru. M = Si, M′= Os). 1,1,2,2 Tetramethyldisilane reacts with [Me3MRu(CO)4]2(M = Si or Ge) to afford the compound Ru2(CO)6(µ-SiMe2)3. The heterocyclic complex [Me2SiOs(CO)3]3 results from the reaction of Me5Si2H and Os(CO)4H2. In general, the silicon-ruthenium and silicon-osmium containing products are obtained in low yield, apparently due to the disproportionation of Me5Si2H and Me4Si2H2 to polysilanes.Keywords
