Synthesis of Exceptionally Stable Iron and Rutheniumη1-tetrahedro-Tetraphosphorus Complexes: Evidence for a Strong Temperature Dependence of M−P4 π Back Donation
摘要:
At variance with white phosphorus, the most reactive allotrope of the element, which is unstable and ignites spontaneously in air, the new η1 -tetrahedro-tetraphosphorus complexes [Cp*M(PR3 )2 (η1 -P4 )]Y (M=Fe, Ru; Y=Cl, PF6 , BPh4 , BAr$\rm{^{\prime }_{4}}$; Cp*=C5 Me3 the structure of the [Cp*Fe(Ph2 PCH2 CH2 PPh2 )(η1 -P4 )]+ ion is depicted) exhibit a surprising and unprecedented thermal stability and an astonishing reluctance to react with oxygen and other oxidants.
