Abstract

The iron(0) dinitrogen complexes [Fe(N₂ )(PP₃^R )] (PP₃^R = P(CH₂ CH₂ PR₂)₃ , R=Ph, iPr, Cy) were synthesized by reduction of the precursor chloro complexes with potassium graphite. On reaction with triflic acid, [Fe(N₂ )(PP₃^R)] complexes afforded ammonia and hydrazine in yields of up to 23 and 16 % respectively. The complex [Fe(N₂)(PP₃^Ph)] which has only been previously synthesized in situ, has now been isolated and fully characterized by ¹⁵N NMR spectroscopy and by X-ray crystallography.
