Description:
The reaction of Cp(CO)2FeI with 2-ethynylpyridine under Sonogashira conditions [5% PdCl2(PPh3)2, 10% CuI, THF–NEt3(2:1)] afforded the title binuclear μ-pyridylvinylidene FePd complex (FePd1) as a benzene solvate, [FePd(C5H5)(C7H5N)I(CO)2]·C6H6, in a very low yield rather than the expected irono-pyridylethynyl complex Cp(CO)2Fe—C[triple-bond]C-(2-C5H4N). The Fe and Pd atoms inFePd1are bridged by carbonyl and pyridylvinylidene ligands, the pyridyl N atom being bonded to the palladium atom. The use of equimolar amounts of PdCl2increases the yield ofFePd1to 12%. The reaction pathway leading toFePd1is proposed.
