So far,three major classes of hydrogenase have been identified,members of each featuring either an FeFe,a NiFe,or an Fe core.The[FeFe]-and[NiFe]-H2ases have been shown to mediate the interconversion of dihydrogen with protons and electrons at high rates and at potentials very close to those bounded by thermodynamics.While hydrogenases have been utilized in fuel cells,their practical implementation is limited.Moreover,scarcity and high cost of platinum also limit widespread use in hydrogen energy economy.Thus,the development of molecular catalysts for H2 evolution is to harness complexes of earth-abundant metals such as Cu,Ni,Fe,Co,Mn and Mo.In a view to exploiting H2-evolution catalysts,we have explored the reaction of diphenylphosphine sulfide with Fe3(CO)12.Herein,we wish to report our findings.Reaction of diphenylphosphine sulfide with Fe3(CO)12 produces (μ-Ph2P)Fe2(CO)6(μ4-S)Fe2(CO)6(μ-κ2S,P-SPPh2) (1),(μ-κ2S,P-SPPh2)Fe2(CO)6(μ3-κ2S∶κP-SPPh2)Fe(CO)4 (2) and[(μ-Ph2P)Fe2(CO)6]2(μ4-S2) (3).Electrochemical studies reveal that 3 can efficiently catalyze H2 production.
