Abstract

The octaferrocenyl cluster [Ag₈(SeCH₂Fc)₈(PPh₃)₄] 3 can be prepared in good yield from FcCH₂SeSiMe₃1 and solubilized AgOAc. The reagent 1 and disubstituted 1,1′-fc(CH₂SeSiMe₃)₂2 are themselves prepared in good yield from Li[SeSiMe₃] with FcCH₂Cl and fc(CH₂Cl)₂, respectively. Reaction of 2 with [Zn(OAc)₂(tmeda)] yields the dimeric complex [{Zn(fc(CH₂Se)₂)(tmeda)}₂] 4. The structures of 3, 4 and di(ferrocenylmethyl)diselenide 5, as determined by single crystal X-ray crystallography, are reported.
