Abstract

The reaction of [W(≡CC≡CSiMe₃)(CO)₂(Tp∗)] (Tp∗ = hydrotris(3,5-dimethylpyrazol-1-yl)borate) with [ⁿBu₄N]F and selenium in the presence of [RuCl(PPh₃)₂(η-C₅H₅)] affords a mixture of the tricarbido complex [WRu(μ-CCC)(CO)₂(PPh₃)₂(η-C₅H₅)(Tp∗)] and the selenoxopropadienylidene (C₃Se) complex [WRu(μ-CCCSe)(CO)₂(PPh₃)₂(η-C₅H₅)(Tp∗)], both of which were structurally characterized. The formation of the bimetallic C₃Se complex is consistent with the intermediacy of the salt [ⁿBu₄N] [W(≡CC≡CSe)(CO)₂(Tp∗)], which could be observed spectroscopically and computationally interrogated, but not yet isolated.
