Thioether complexes of tungsten hexacarbonyl

The preparation of a series of organic and organometallic thioethers R3MSR' (M = C,Si,Ge, or Sn) is reported.From these, several new compounds of type 1 are synthesized, some of which contain para-substituted aryl functions for R and R'.In hexane solution in the carbonyl streching region of the ir the uv there is evidence for a degree of multiple bonding, at least in the M - S - WW - CO portion of these molecules.Multiple bonding extending into aromatic R or R'is small or non-existent and cannot be assessed precisely because of spontaneous decomposition of the complexes.All the complexes undergo a thermally initiated decomposition, the case of which depends on the nature of R, R', and M.The unusual W(I) thiolate cis-2 is the termal decomposition product.
