Abstract:

Two new model complexes related to the [FeFe]-hydrogenase active site (mu-SCH2CCCH2Cl)(2)Fe-2(CO)(6) (1) and (mu-SC2H5)(mu-SCH2CCCH2Cl)Fe-2(CO)(6) (2) were obtained by treating (mu-LiS)(2)Fe-2(CO)(6) with 1, 4-dichloro-2-butyne. By controllable CO displacement of 1 or 2 with PPh3, mono- and di-substituted complexes, namely [mu-SCH2CCCH2Cl)(2)Fe-2(CO2)(6-x)(PPh3)(x)] (3, X = 1; 5, X = 2), and [(mu-SC2H5)(mu-SCH2CCCH2Cl)Fe-2(CO)(6-x)(PPh3)(x)] (4, X = 1; 6, X = 2) could be prepared in moderate yields. Treatment of 1 or 2 with bis(diphenylphosphino) ethane (dppe) afforded a double butterfly complex [(mu-SCH2CCCH2Cl)(2)Fe-2(CO)(5)](2) (mu-dppe) (7) and (mu-SC2H5)(mu-SCH2CCCH2Cl)Fe-2(CO)(5)](2) (1-dppe) (8), respectively. These molecular structures were characterized by FT-IR, H-1, P-31 NMR spectra and the molecular structures of complexes 1, 3, 6 and 8 were determined by single crystal X-ray analyses. The electrochemistry of 1-8 was studied and the electrocatalytic property of 1 was investigated for proton reduction in the presence of acetic acid.
