Synthesis and characterizations of a new BIS(tricarbonyl-iron)‎ compound containing ferrocenethiolate ligand and its trimethylphosphine derivatives : x-ray structure of BIS(µ2-ferrocenethiolato)‎ BIS(tricarbonyl-iron)‎

Abstract EN

The synthesis and characterization of new ferrocene derivatives of the type Fe2(CO)6 S2Fc2 (Fc=Ferrocenyl) is reported.

These compounds have been prepared by the reaction of the Fe2 (CO)9 complex with a stoichiometric amount of the diferrocenyl disulfur compounds in a near refluxing THF solvent.

Furthermore, the consequent mono–and di– trimethylphosphine derivatives were synthesized by photolysis or thermolysis of the Fe2 (CO)6 S2Fc2 complex in the presence of the phosphine ligands Also, the compounds: Fe2(CO)6S2Fc2 (1) Fe2(CO)5 PMe3S2Fc2 (2), and Fe2(CO)4 (PMe3)2S2Fc2 (3) have been fully characterized by IR,1H, 13C, and 13P NMR spectroscopy.

Fe2(CO)6 S2Fc2 crystal structure determinations confirm that the two ferrocenyl groups are trans to each other.
