Synthesis, Structure, and Electrochemical Properties of 2,3,4,5-Tetraphenyl-1-Monophosphaferrocene Derivatives.

ABSTRACT: Heteroleptic 2,3,4,5-tetraphenyl-1-monophosphaferrocene [FeCp(η⁵-PC₄Ph₄)] was obtained at a 62% yield through the reaction of lithium 2,3,4,5-tetraphenyl-1-monophosphacyclopentadienide Li(PC₄Ph₄) (1) with [FeCp(η⁶-C₆H₅CH₃)][PF₆]. The structure of 1-monophosphaferrocene 2 and its W(CO)₅-complex 3 were confirmed by multinuclear NMR and single-crystal X-ray diffraction study and further supported by DFT calculations. Cyclic voltammetry demonstrated that [FeCp(η⁵-PC₄Ph₄)] 2 has a quasi-reversible oxidation wave. The comparison of the properties of phosphaferrocene 2 with those of W(CO)₅-complex
