Dithioesters R1C(S)SR2 react with to afford binuclear complexes (CO)3FeC(R1)S(R2)SFe(CO)3 (I) in which the organic ligand gives six electrons to the Fe2(CO)6 skeleton.Spectroscopic data show the existence of a carbon-iron ? bond with creation of a chiral center.This is confirmed by single-crystal X-ray structure determination of complex Ig (R1=C4H3S, R2=Me).This structure shows that coordination imposes important geometrical constraints. 13C NMR studies reveal a temperature dependant dynamic behaviour for complexes I in solution.The carbonyl fluxionality occurs around each metal atom independently.Electrophilic substitution of the coordinated organic ligand may occur despite the complex fragility in a basic medium or in the presence of oxidizing agents.
IRON CARBONYL COMPLEXATION OF DITHIOESTERS. FORMATION OF A CHIRAL CARBON CENTER ?-BONDED TO AN IRON ATOM

Dithioesters react with diiron nonacarbonyl to afford binuclear complexes resulting from coordination of the carbon-sulfur double bond to the two iron atoms and donation of two electrons from the S-alkyl group to one iron center.This novel mode of complexation creates a carbon-iron single bond and a chiral center at the carbon atom bonded to the metal, as shown by the spectroscopic studies and by a X-ray structure determination.
