Ferrocenyl sulfinylimide and diferrocenyl sulfurdiimide, Fc - NSO and Fc(NSN)Fc

Article abstract of DOI:10.1002/zaac.19966220913

The reactions of ferrocenylamine, Fc - NH₂ (1), with thionyl chloride and sulfur dichloride in hexane solution in the presence of triethylamine lead to the title compounds Fc - NSO (2) and Fc(NSN)Fc (3), respectively. 2 and 3 have also been obtained in reactions of the silylated ferrocenylamine, Fc - NH(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 = ¹Bu (4 a), SiMe₃ (4b)) by reaction with the lithium derivative of silylated amines, LiN(SiMe₃)R (R = Fc, ¹Bu, 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 Fc - NSO (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.
