Synthesis and Structural Characterization of Diiron Dithiolate Complex (u-SCH2)2NCH2PhFe2(CO)52(Ph2PCH2CH2CH2PPh2) with Bridging Diphosphine Ligand

摘要

A novel diiron dithiolate complex (n-SCH)22NCH2PhFe2(CO)5(Ph2PCH2CH2CH2PPh2) (1), as the active site model of FeFe-hydrogena.ses, has been prepared and structurally characterized. The title complex could be prepared by reaction of (μ-SCH2)2NCH;PhFe2(CO)6 (A) with 1,3-W.y(diphenylphosphinopropane) (DPPP) (PhaPCTTCHjCFkPPh2) in the presence of MejNO-lHjO in MeCN at room temperature in 54 yield. The new complex 1 was characterized by IR, 'H NMR and ~(31)P NMR spectroscopy,
