The condensation reaction of ferrocenecarbaldehyde with G SRC="/images/gifchars/beta2.gif" BORDER=0 ALIGN="middle">-mercaptoethylamine gives FcCHN(CH2)2SH [Fc =(
ges/gifchars/eta.gif" BORDER=0 >5-C5H5)Fe(ges/gifchars/eta.gif" BORDER=0 >5-C5H4)], which is easily oxidized to the disulfide derivative FcCHN(CH2)2S2(CH2)2NCHFc.Treatment of FcCHN(CH2)2SH with [AuCl(PPh3)] in the presence of Na2CO3 affords the thiolate gold(I) complex[FcCHN(CH2)2S(AuPPh3)]. Further reaction of the latter with various molar ratios of [Au(TfO)PPh3] (TfO =trifluoromethanesulfonate) leads to di-, tri-, and tetranuclear gold species in which the metallic centers are bondedto the sulfur and nitrogen ligands. The reaction of FcCHN(CH2)2SH with [Au2(TfO)2(ges/entities/mgr.gif">-dppf)] in a 1:1 or 1:2molar ratio has also been carried out to give [FcCHN(CH2)2S{Au2(ges/entities/mgr.gif">-dppf)}]TfO or [FcCHN(CH2)2S{Au2(ges/entities/mgr.gif">-dppf)}2](TfO)3. The crystal structure of [FcCHN(AuPPh3)(CH2)2S(AuPPh3)2](TfO)2 reveals short gold-goldinteractions.
