Reaction of (M = Mo or W) with a slight excess of RS(CH2)2SR (R = Ph, 4-MeC6H4 or 4-FC6H4) in CH2Cl2 at room temperature gave >.The molecular structure of has been determined by X-ray crystallography.It shows that the tungsten has essentially capped-octahedral geometry with a carbonyl ligand in the unique capping position.Low-temperature 13C NMR studies on the tungsten complexes suggest that their structures in solution are similar to the solid-state structure found.Reaction of with 2 equivalents of PhS(CH2)2SPh in CH2Cl2 afforded >I which was reduced by Li-n-Bu to cis-2>.Equimolar quantities of (M = Mo or W) and MeS(CH2)2S(CH2)2SMe reacted in CH2Cl2 to give > and >.The latter was converted in CHCl3 into >, the molecular structure of which is essentially a capped octahedron with a carbonyl ligand in the unique capping position.
