Abstract:
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[triple-bond]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.
