  Reactivity of multi-site bound allenylidene towards alkynes and silica gel †

  摘要：

  Heating the allenylidene species [Ru3(CO)9(μ-CO)(μ3-CCCPh2)] in the presence of alkynes RC2R (R = Me or Ph) led to formation of the novel complexes [Ru3(CO)9{μ3-C(R)C(R)C2CPh2}] (R = Me or Ph) and [Ru4(CO)12{μ4-C(Ph)C(Ph)CCCPh2}], shown by X-ray diffraction to contain C5 ligands formed through carbon–carbon bond formation with the α-carbon of the allenylidene unit. Adsorption of [Ru3(CO)9(μ-CO)(μ3-CCCPh2)] onto silica gel at room temperature leads to formation of the acetylide species [Ru3(CO)9(μ-H){μ3-CCC(Ph)2OH}], whereas reaction of [Ru3(CO)9(μ-CO){μ3-CCC(Ph)Me}] with silica gel affords [Ru3(CO)9(μ-H){μ3-CCC(Ph)CH2}], containing an ene-yne ligand. Some insights into the mechanisms by which the transformations take place are given. p
