NOVEL BRIDGING SULFIDE ANION COMPLEXES OF THE HEXACARBONYLDIIRON UNIT - NEW ROUTE TO ALKYLTHIO COMPLEXES OF IRON

The interesting iron-sulfur cluster complex, µ-dithio-bis-(tricarbonyliron), I, has been known for 20 years since its first preparation by Hieber and Gruber, and its structure, as indicated in I, was determined by Wei and Dahl. Although new procedures for the preparation of I have been developed recently by Russian workers, only little work has been reported concerning the chemical transformations of this complex. Of some interest is the reaction of S2Fe2(CO)6 with GeCl2 precursors, which resulted, it was claimed, in the insertion of GeCb into the Fe-Fe bond. © 1979, American Chemical Society.
