Abstract: The pound [(μ-SCH2)2CH2)Fe2(CO)5][Fc(PPh2)CHO] (3) has been prepared by
reaction of plex [(μ-SCH2)2CH2]Fe2(CO)6 (1) with Fc(PPh2)CHO (2) in the presence of
CO-removing reagent Me3NO·2H2O. Then, 3 reacted with benzaldehyde and pyrrole to synthesize a
25
novel
[FeFe]-hydrogenase model [(μ-SCH2)2CH2)Fe2(CO)5][(PPh2)H2FcPh3P] (4), which
contained photosensitive group. 4 was characterized by 1H NMR, 31P NMR, 13C NMR and
elemental analysis. The attribute of photoinduced electron transfer was also studied by means of
UV-Vis absorption and fluorescence emission spectrum.
