Synthesis, Characterization and Reactivity of Functionalized Trinuclear Iron-Sulfur Clusters - A New Class of Bioinspired Hydrogenase Models
Sprache des Titels:
The air- and moisture-stable iron?sulfur carbonyl clusters
Fe3S2(CO)7(dppm) (1) and Fe3S2(CO)7(dppf) (2) carrying the
bisphosphine ligands bis(diphenylphosphanyl)methane
(dppm) and 1,1´-bis(diphenylphosphanyl)ferrocene (dppf)
were prepared and fully characterized. Two alternative synthetic
routes based on different thionation reactions of triiron
dodecacarbonyl were tested. The molecular structures of the
methylene-bridged compound 1 and the ferrocene-functionalized derivative 2 were determined by single-crystal X-ray
diffraction. The catalytic reactivity of the trinuclear iron?sulfur cluster core for proton reduction in solution at low overpotential was demonstrated. These deeply colored bisphosphine-bridged sulfur-capped iron carbonyl systems are discussed as promising candidates for the development of new
bioinspired model compounds of iron-based hydrogenases.
