Crystal structure of μ-carbonyl-1:2κ(2) C:C-carbonyl-1κC-(1η(5)-cyclopentadienyl)iodido-2κI-[μ-2-(pyridin-2-yl)ethene-1,1-diyl-1κC (1):2κ(2) N,C (1)]ironpalladium(Fe—Pd) benzene monosolvate
The reaction of Cp(CO)(2)FeI with 2-ethynylpyridine under Sonogashira conditions [5% PdCl(2)(PPh(3))(2), 10% CuI, THF–NEt(3) (2:1)] afforded the title binuclear μ-pyridylvinylidene FePd complex (FePd1) as a benzene solvate, [FePd(C(5)H(5))(C(7)H(5)N)I(CO)(2)]·C(6)H(6), in a very low yield rather...

Sumario: | The reaction of Cp(CO)(2)FeI with 2-ethynylpyridine under Sonogashira conditions [5% PdCl(2)(PPh(3))(2), 10% CuI, THF–NEt(3) (2:1)] afforded the title binuclear μ-pyridylvinylidene FePd complex (FePd1) as a benzene solvate, [FePd(C(5)H(5))(C(7)H(5)N)I(CO)(2)]·C(6)H(6), in a very low yield rather than the expected iron o-pyridylethynyl complex Cp(CO)(2)Fe—C≡C-(2-C(5)H(4)N). The Fe and Pd atoms in FePd1 are bridged by carbonyl and pyridylvinylidene ligands, the pyridyl N atom being bonded to the palladium atom. The use of equimolar amounts of PdCl(2) increases the yield of FePd1 to 12%. The reaction pathway leading to FePd1 is proposed. |
