Synthesis of Dicarbonyl(η4-tricarbonylcobaltacyclopentadiene)cobalt Complexes from Co2(CO)8. A General Route to Intermediates in Cobalt Carbonyl Mediated Alkyne Trimerization

We have shown that cobaltacyclopentadiene complexes, derived from cobalt carbonyl and two alkyne molecules and long believed to be intermediates in cyclotrimerization as well as in the formation of the (three-alkyne-derived) flyover complexes, can be isolated in selected cases if the mono(alkyne)-Co2(CO)6 complexes are treated at room temperature with just 1 equiv of alkyne in the presence of trimethylamine N-oxide. The complex (PhC=CHCMe= CMe)Co2(CO)5 has been characterized by X-ray crystallography.

Cluster Synthesis. 28. New platinum-cobalt carbonyl cluster complexes and products obtained from their reactions with alkynes

The reaction of Pt(COD)2, COD = 1,5-cyclooctadiene, with Co2(CO)8 in cyclohexane solvent at 25°C has yielded the new compounds PtCo2(CO)7(COD) (1, 3%) and Pt2Co2(CO)8(COD) (2, 31%) and the known compound Co4(CO)12 (3, 14%). Compounds 1 and 2 were characterized by single-crystal X-ray diffraction analyses. Compound 1 contains a triangular cluster of one platinum and two cobalt atoms with a carbonyl ligand bridging the Co-Co bond. Compound 2 consists of a tetrahedral cluster of two platinum atoms and two cobalt atoms. The Pt-Pt bond is weak, 2.9546 (6) A?. Compound 2 reacts with EtC2Et to yield the new complex Pt2Co2(CO)8(μ3-EtC 2Et)2 (4, 8%), and it reacts with PhC2Ph to yield the new complex Pt3Co2(CO)6(COD)2(μ 3-PhC2Ph)2 (5, 22%). Compounds 4 and 5 were characterized crystallographically. Compound 4 contains a butterfly cluster of two cobalt and two platinum atoms. The two platinum atoms occupy the hinge positions and are joined by a short Pt-Pt bond, 2.4945 (7) A?. Triply bridging EtC2Et ligands bridge the two Pt2Co triangles. Compound 5 contains a bow-tie cluster of three platinum and two cobalt atoms with a platinum atom in the center. Triply bridging PhC2Ph ligands bridge the two Pt2Co triangular groupings.
