| Popis: | The introduction of an alkylcarbonyl side chain into the aromatic ring of some chloro-substituted benzenes has been achieved under mild conditions by the Yanovsky-type reaction of (η6chloroarene)(η5-cyclopentadienyl) cationic complexes of iron or ruthenium with silyl enol ethers. An ester side chain has been introduced similarly using ethyl trimethylsilylacetate. The resulting (η5-chlorocyclohexadienyl)(η5-cyclopentadienyl) adducts derived from the ruthenium salts are more stable than their iron analogues. Treatment of the neutral ruthenium adducts with 2,3-dichloro-5,6-dicyano-1,4-benzoquinone gives moderate yields of the [η6-(substituted chloroarene)(η5-Cp)]Ru+PF−6 salt, together with the decomplexed substituted chloroarene. |
