| Abstract: | In attempt to synthesize suitable [FeFe] hydrogenase model complexes, 2-methoxypropane-1,3-dithiole and 4-methyl-4-hydroxy-1,2-dithiolane were reacted with Fe3(CO)12 to give the respective complexes [Fe2(CO)6(H3COCH(CH2S)2)] and [Fe2(CO)6(HOC(CH3)(CH2S)2)]. The compounds were characterized by 1H and 13C NMR spectroscopy, mass spectrometry and elemental analysis. In addition, their electrochemical properties were investigated by cyclic voltammetry and compared with that of [Fe2(CO)6(HOC(CH2S)2)] known from literature. |
