Abstract

The pentamethylcyclopentadienyl tungsten carbonyl acetylide complexes (C₅Me₅)W(CO)₃(CCR), (1) R = Ph, CH₂OMe, Prⁿ and C(Me) = CH₂, reacted with an acidic solution of hydrogen peroxide at room temperature, giving the oxo-peroxo acetylide complexes (C₅Me₅)W(O)(O₂)(CCR) (2) in good yields. Upon treatment with triphenylphosphine the complexes (2) lost one oxygen atom to afford the corresponding dioxo complexes (C₅Me₅)W(O)₂(CCR) (3). These oxo-peroxo and dioxo complexes were characterized by spectroscopic methods and, for (C₅Me₅)W(O)₂(CCPh) (3a), was further identified by single crystal X-ray diffraction study.
