摘要：

The photolysis of M(CO)(4)(dppe) (M = Mo, W) and C-60, C-70 or dimethyl fumarate (dmf) in chlorobenzene provides M(CO)(3)(dppe)(eta(2)-C-60) (M = MO, 1; M = W, 2), Mo(CO)(3)(dppe)(eta(2)-C-70) (3), and W(CO)(3)(dppe)(eta(2)-dmf) (4), the structures of which have been determined by X-ray crystallography. Distorted octahedral geometries are found for the metal centers in all cases, with the dppe and olefin ligands in a mer configuration, and the C-60 and C-70 complexes display significant secondary interactions between the fullerene moiety and the phenyl groups of the diphosphine ligand. Furthermore, from P-31 NMR studies, two isomers of 3 are observed.
