The monothiolate derivatives of tungsten(VI) chloride, (R=Me, Et, cyclohexyl, Bui, But, CH2Ph, or Ph), have been found to be unstable with respect to at least two modes of degradation.Heterolytic cleavage of the carbon-sulphur bond to generate a carbonium ion, which can further abstract chloride to give WSCl4 + RCl, is the preferred pathway if the R(+) ion is relatively stable.The intermolecular elimination of R2S2 is the alternative route for degradation and is the exclusive one for R=Ph, where the carbonium ion is very unstable.The only pure compounds which have been isolated are and and even these slowly decompose at room temperature over a period of a few weeks.
