  • Reactions of diarsines with bi- and tri-metallic carbonyl complexes containing cobalt

    Reaction of the diarsines As2R4 (R = Me or Ph) with alkyne-bridged dicobalt hexacarbonyl complexes leads to products with bridging (AsR2)2O ligands and to the production of simple AsR3 substituted complexes; alkylidyne tricobalt nonacarbonyl complexes exhibit parallel reactivity with As2R4. Thermolysis of the complex [Co2(μ-PhCCPh)μ-(AsMe2)2O}(CO)4] gives the tetra-substituted complex, [Co2(μ-PhCCPh)μ-(AsMe2)2O}2(CO)2]. Reaction of the heterometallic complex [(OC)3Coμ-C2(CO2Me)2}MoCp(CO)2] with As2Ph4 affords [(HO)Ph2As}(OC)2Coμ-C2(CO2Me)2}MoCp(CO)2], supporting the suggestion of a possible hydrolytic mechanism for the formation of the (AsR2)2O bridged complexes.
    二砷化物As2R4(R = Me或Ph)与炔桥联二钴六羰基配合物的反应产生了具有桥联(AsR2)2O配体的产物,以及生成简单的AsR3取代配合物;烷基亚砜三钴壬羰基配合物表现出平行的反应性。复杂配合物[Co2(μ-PhCCPh)μ-(AsMe2)2O}(CO)4]的热分解产生了四取代配合物,[Co2(μ-PhCCPh)μ-(AsMe2)2O}2(CO)2]。异金属配合物[(OC)3Coμ-C2(CO2Me)2}MoCp(CO)2]与As2Ph4反应生成[(HO)Ph2As}(OC)2Coμ-C2(CO2Me)2}MoCp(CO)2],支持了(AsR2)2O桥联配合物形成的可能水解机制的建议。

    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.
