AbstractAbbreviations and Nomenclature: Fc = η1‐ferrocenyl, CpFe(C5H4‐); Cp = η5‐cyclopentadienyl, η5‐C5H5. Compounds containing the —NSO group are designated as either thionylimides, sulfinylimides or N‐sulfinylamines. The systematic name is imido oxo sulfuranes(IV).
The reactions of ferrocenylamine, FcNH2 (1), with thionyl chloride and sulfur dichloride in hexane solution in the presence of triethylamine lead to the title compounds FcNSO (2) and Fc(NSN)Fc (3), respectively, 2 and 3 have also been obtained in reactions of the silylated ferrocenylamine, FcNH(SiMe3) (1b), with thionyl chloride. The ferrocenyl sulfinylimide 2 has been converted to sulfurdiimides such as Fc(NSN)Fc (3) and Fc(NSN)R (R = tBu (4a), SiMe3 (4b)) by reaction with the lithium derivative of silylated amines, LiN(SiMe3)R (R = Fc, tBu, SiMe3). The new ferrocenyl compounds 2–4 have been characterized by their NMR spectra, and their electrochemical behaviour has been studied. The molecular structure of FcNSO (2) has been determined by an X‐ray structure analysis; the sulfinylimide has the Z configuration, and the —NSO group is coplanar with the cyclopentadienyl ring to which it is attached.
