Lithium, sodium, and potassium ferrocenecarboselenoates were synthesized in good yields by the reaction of ferrocenoyl chloride with the corresponding metal selenides. In air, the saltsquickly oxidized to give diferrocenoyl diselenide. The salts readily reacted with alkyl and organo-germanium, -tin and -lead halides to give the corresponding Se-alkyl and Se-organo Group-14 element ferrocenecarboselenoates [(FcCOSe)xMPh4x (M = Ge, Sn, Pb; x = 13) in moderate to good yields. In contrast, the reaction of the sodium and potassium salts with trimethylsilyl chloride led to O-trimethylsilyl ferrocenecarboselenoate FcCSeOSiMe3. Treatment of the O-silyl ester with RbF and CsF led to rubidium and cesium ferrocenecarboselenoates, respectively, in good yields. The structures of FcCOSetBu, (FcCOSe)2SnPh2, and FcCOSePbPh3 were revealed by X-ray molecular structure analysis.
