Abstract

The synthesis of a series of iron and ruthenium complexes with the new ligand PPⁱ₃ (1) P(CH₂CH₂P ⁱPr₂)₃ is described. The iron(0) and ruthenium(0) dinitrogen complexes Fe(N₂)(PPⁱ₃) (4) and Ru(N₂)(PPⁱ₃) (5) were synthesized by treatment of the iron(ll) and ruthenium(ll) cationic species [FeCI(PP ⁱ₃)]⁺ (2) and [RuCI(PPⁱ₃)]⁺ (3) with potassium graphite under a nitrogen atmosphere. The cationic dinitrogen species [Fe(N₂)H(PP ⁱ₃)]⁺ (6) and [Ru(N₂)H(PP ⁱ₃)]⁺ (7) were prepared by treatment of 4 and 5, respectively, with 1 equiv of a weak organic acid. Complexes 2 · [BPh₄], 3-[BPh₄], 4, 5, and 6-[BF₄] were characterized by X-ray crystallography. The structural characterization of 5 is the first report for a ruthenium(0) dinitrogen complex. © 2009 American Chemical Society.
