Independently unstable thiocarbonylphosphorane or arsorane ligands SCAR (A = P, As) are observed in the salts [W(η-,-SCAR)(CO)(Tp*)]PF [AR = PCy, PMePh: = 0, 1, 2, AsMePh; Tp* = tris(dimethylpyrazolyl)borate] which arise from the reactions of phosphonio- or arsoniocarbynes [W(≡CAR)(CO)(Tp*)] with sulfur.
