Abstract:Diiron carbonyl complexes [Fe 2 (CO) 5 (m-pdt)(k 1 -L)] 1 and [Fe 2 (CO) 5 (m-Mebdt)(k 1 -L)] 3 were obtained in moderate yields from the parent complexes [Fe 2 (CO) 6 (m-pdt)] and [Fe 2 (CO) 6 (m-Mebdt)] and the chelating diphosphine ligand, L = (Oxydi-2, 1-phenylene)bis(diphenylphosphine). In addition, complexes [Fe 2 (CO) 5 (m-pdt)(k 1 -LO)] 2 and [Fe 2 (CO) 5 (m-Mebdt)(k 1 -LO)] 4 containing oxidized phosphine (P = O) were obtained as side products of the reaction. In all the four complexes only one phosph… Show more
Reaction of the precursor complexes [Fe2(μ‐SCH2Ph)2(CO)6] 1 and [Fe2(μ‐SEt)2(CO)6] A with the phosphine ligand (L=P(PhOMe‐p)3) yielded the mono‐substituted complexes [Fe2(μ‐SCH2Ph)2(CO)5(P(PhOMe‐p)3)] 2 and [Fe2(μ‐SEt)2(CO)5(P(PhOMe‐p)3)] 3. All the complexes were characterized by various spectroscopic techniques. X‐ray crystal structure has been reported for complex 3. The reduction potentials of the phosphine substituted complexes 2 and 3 appeared at more negative potentials in comparison to the precursor complexes 1 and A. Complexes 1–3 were catalytically active towards proton reduction in the presence of acids.
