Investigating N₂ Fixation Using a Bulky Fe(bisphosphine)₂ Framework.

ABSTRACT: An iron(0) dinitrogen complex incorporating highly sterically encumbered bisphosphine ligands, Fe(N₂)(dibpe)₂ (dibpe = iBu₂PCH₂CH₂PiBu₂), ^{i Bu}1·N₂, has been prepared and thoroughly characterized, and its N₂ fixation reactivity assessed. ^{i Bu}1·N₂ is a more hindered analogue of Fe(N₂)(depe)₂ (depe = Et₂PCH₂CH₂PEt₂), ^Et1·N₂, which has previously been shown to be an efficient N₂ reduction catalyst with unusual selectivity for N₂H₄, and it was anticipated that greater bulk might make ^{i Bu}1·N₂ less prone
