| 英文摘要 | a [fefe]-hydrogenase model (1) containing a chelating diphosphine ligand with a pendant amine was readily oxidized by fc(+) (fc = cp2fe) to a (fefei)-fe-ii complex ([1](+)), which was isolated at room temperature. the structure of [1](+) with a semibridging co and a vacant apical site was determined by x-ray crystallography. complex [1](+) catalytically activates h-2 at 1 atm at 25 c in the presence of excess fc(+) and p(o-tol)(3). more interestingly, the catalytic activity of [1](+) for h-2 oxidation remains unchanged in the presence of ca. 2% co. a computational study of the reaction mechanism showed that the most favorable activation free energy involves a rotation of the bridging co to an apical position followed by activation of h-2 with the help of the internal amine to give a bridging hydride intermediate. |
