Chalcogenoketones (Fc)2C=X 1a (X = S, Fc = Ferrocenyl), 1b (X = Se), and 1c (X = Te) are synthesized by reaction of diferrocenylketone with P4S10, bis(dimethylaluminum)-selenide; bis(dimethylaluminum)-telluride, respectively.Reaction with (M = Cr, Mo, W) yields, for 1a, the complexes <(Fc)2C=S> 2ad (M = Cr), 2af (M = W), and 3; and for 2b, the complex <(Fc)2C=Se> 2bf.Telluroketone 1c does not form a complex; instead detelluration takes place and tetraferrocenylethylene (Fc)2C=C(Fc)2 is obtained quantitatively.The structure of compound 3 has been determined by X-ray diffraction study.All compounds, except the extremely air-sensitive chalcogenoketones 1b and 1c, have been characterized by the usual spectroscopic and analytical methods.
