Abstract

Interaction of Ru5C(CO)15 with C60 in refluxing chlorobenzene followed by PPh3 or dppe (1,2-bis(diphenylphosphino)ethane) forms Ru5C(CO)11(PPh3)(μ3222-C60) (1) or Ru5C(CO)10-(μ-η11-dppe)(μ3222-C60) (2), isolated in 19% and 14% yields, respectively, after chromatography. An analogous reaction of Ru5C(CO)15 with C60 followed by dppf (1,1′-bis(diphenylphosphino)ferrocene) initially forms both Ru5C(CO)111-dppf)(μ 3222-C 60) (3) and Ru5C(CO)10(μ-η11-dppf)(μ3222-C60) (4), but further thermolysis of 3 in refluxing chlorobenzene converts it to 4. Direct interaction of Ru5C(CO)14(PPh3) (5), Ru5C(CO)13(dppe) (6), and Ru5C(CO)13(dppf) (7) with C60 in refluxing chlorobenzene also provides 1, 2, and 4 in isolated yields of 21%, 27%, and 20%, respectively. Interaction of PtRu5C(CO)16 or PtRu5C-(CO)14(COD) with C60 followed by dppe in refluxing chlorobenzene forms PtRu5C(CO)112-dppe)(μ 3222-C 60) (8) (7% and 23% yields, respectively). Substitution of the COD ligand in PtRu5C(CO)14(COD) by dppe at room temperature provides PtRu5C(CO)142-dppe) (9). Compound 9 does not react with C60 to give 8. All new compounds have been characterized by a combination of analytical and spectroscopic methods, and the molecular structures of compounds 1, 2, 4, 7, 8, and 9 have been determined by single-crystal X-ray diffraction studies.
