Abstract

The iron(0) dinitrogen complexes [Fe(N2 )(PP3R )] (PP3R = 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 )(PP3R)] complexes afforded ammonia and hydrazine in yields of up to 23 and 16 % respectively. The complex [Fe(N2)(PP3Ph)] which has only been previously synthesized in situ, has now been isolated and fully characterized by 15N NMR spectroscopy and by X-ray crystallography.
