Addition of organolithium nucleophiles to the diiron allenyl complex [Fe2(CO)6(μ-PPh2){μ-η1: η2 α,β-(H)Cα=Cβ =CγH2}]:Synthesis and characterization of organodiiron-coordinated β,γ-unsaturated ketones

Abstract:

The binuclear allenyl complex [Fe2(CO)6(μ-PPh2){μ-η 1:η2α,β-(H)C α=Cβ=CγH2}] (1) has been prepared, and its reactivity with organolithium nucleophiles is described. Prop-2-yne bromide reacts with [Fe2(CO)7(μ-PPh2)]-Na +, via an SN2 mechanism, to give [Fe2(CO)6(μ-PPh2){μ-η1: η2α,β-(H)Cα=C β=CγH2}], the first example of a phosphido-bridged allenyl complex. The molecular structure of [Fe2(CO)6(μ-PPh2){μ-η 1:η2-(H)Cα=Cβ=C γH2}]: (1) was determined by single-crystal X-ray diffraction and shows tha...
