The complex [FeH(H2)(Me2PCH2CH2PMe2)2][BPh4] reacts with various substituted cyclopropenes to give mixtures of propenes and cyclopropanes. No further acid is required and the solvent, acetone, appears to be a ready source of protons. The only iron-containing product isolated is [{FeH(Me2PCH2CH2PMe2)2}2(µ-Me2PCH2CH2PMe2)][BPh4]2, the structure of which was determined by X-ray crystal structure analysis. Evidence that a direct iron–cyclopropene interaction is necessary for hydrocarbon reduction to occur is outlined and the validity of this iron system as a model for nitrogenase function is assessed.
