Resumen

The compounds cis-(η⁵-C₅Me₅)Re(CO)₂Me₂ and trans-(η⁵-C₅Me₅)Re(CO)₂Et₂ were prepared by alkylation of cis-(η⁵-C₅Me₅)Re(CO)₂Cl₂ using the corresponding organocopper (RCu). Photolysis of cis(η⁵-C₅Me₅)Re(CO)₂Me₂ in frozen toluene-d₈ readily produces the trans-(η⁵-C₅Me₅)Re(CO)₂Me₂. All the compounds were characterized by spectroscopy and analyses, and the stereochemistry assigned from examination of ν(CO) IR intensities; additionally trans-(η⁵-C₅Me₅)Re(CO)₂Et₂ was studied by X-ray crystallography. Crystal data: monoclinic P2₁/m, a = 8.034(8) Å, b = 11.991(8) Å, c = 8.69(2) Å, β = 91.38°, V = 837(2) Å³, Z = 4, λ(Mo Kα) = 0.7107 Å, R_F = 0.0285 and wR₁ = 0.071 for 1670 measured reflections with 5 < 2θ < 50°.
