Funktionelle Trimethylphosphinderivate, VII: Ambivalentes Verhalten von Tetrakis(trimethylphosphin) eisen: Zum Verlauf der Reaktion mit CH₃I

Functional Derivatives of Trimethylphosphine. VII: Ambivalent Behaviour of Tetrakis(trimethylphosphine) iron: Reaction with CH₃I Treatment of the title complex 1a ⇌ 1b with CH₃I in pentane at ambient temperature yields L₄(CH₃)Fel(L = P(CH₃)₃). The reaction is shown to proceed via oxidative addition to the iron(0) isomer 1a. In ether at lower temperature, a reaction with the iron(II) isomer 1b predominates, which leaves its hydridoiron function unchanged. So, a hydridoiron iodide complex is formed, probably by attack on the FeC bond.
