Abstract

Oxidation of the diynyl and diyndiyl complexes [W(C[triple bond, length as m-dash]CC[triple bond, length as m-dash]CH)(CO)3Cp*] (1) and [{W(CO)3Cp*}2(μ-C[triple bond, length as m-dash]CC[triple bond, length as m-dash]C)] (2) affords the corresponding dioxo compounds [W(C[triple bond, length as m-dash]CC[triple bond, length as m-dash]CH)(O)2Cp*] (4) and [{W(O)2Cp*}2(μ-C[triple bond, length as m-dash]CC[triple bond, length as m-dash]C)] (6) via oxo–peroxo intermediates. The molecular structures are consistent with a degree of mixing between the carbon orbitals of the C4(H) fragment and the d4, but not the d0, metal centres. A simple synthesis of the useful reagent WCl(CO)3Cp* is also described.
