Four alkoxo tungsten complexes[Cp₂W(PMe₃)OR]⁺ OTs^-(R=Me,Et, n-Pr, i-Pr) and monohydrido tungsten complex[Cp₂W(H)(PMe₃)]⁺ OTs^- were synthesized and characterized by IR, ¹H NMR and elemental analysis. The U-elimination of these complexes in dimethyl sulfoxide solvent yields monohydrido tungsten complex[Cp₂W(H)(PMe₃)OR]⁺ OTs^- and a ketone or aldehyde.
