【 摘 要 】

Transmetalation between [CpFe(CO)₂I] and arylzinc iodide-lithium chloride complexes proceeds in the presence of catalytic amounts of palladium acetate and N,N,N’,N’-tetramethyl-1,2-cyclohexanediamine to yield the corresponding aryliron complexes [CpFe(CO)₂Ar]. Phenylation of [CpFe(CO)₂I] also takes place when triphenylindium is used under similar conditions. Arylboronic acids undergo arylation in the presence of cesium carbonate and a palladium-N-heterocyclic carbene complex, PEPPSI.  The present methods are useful for the facile synthesis of various functionalized [CpFe(CO)₂Ar]. The products [CpFe(CO)₂Ar] represent an interesting class of aryl metals that undergo several transformation.
