The efficient syntheses of various metallocenyl thioamides using a single-step three-component condensation reaction between the commercially available (dimethylaminomethyl)ferrocene or aminomethylferrocene and another organic amine in the presence of elemental sulfur are described. All new organometallic thioamide derivatives were unambiguously characterized by 1 H and 13 C NMR spectroscopy and mass spectrometry. Furthermore, the structures of five ferrocenyl thioamides determined by X-ray crystallography are presented.
