A series of nine ferrocene chalcogenol derivatives of the type Fe(C5H5)(C5H4EC(O)R) and of nine 1,1'-ferrocene dichalcogenol derivatives of the type Fe(C5H4EC(O)R)2 has been prepared in which the chalcogen (E=S, Se, Te) and the acyl group (C(O)R=benzoyl, 2-thenoyl, ferrocenoyl) were systematically varied.The crucial step of the synthesis includes insertion of the chalcogen E into the Li-C bond of the lithioferrocene to give the chalcogenolate intermediate Fe(C5H5)(C5H4ELi) or Fe(C5H4ELi)2, respectively, to be subsequently treated with the acyl chloride, RC(O)Cl.The 1H and 13C NMR spectra of the new compounds are discussed.
