Virtually all organosulfur compounds react with Fe(0) carbonyls to give the title complexes. These reactions are reviewed in light of major advances over the past few decades, spurred by interest in Fe2(μ-SR)2(CO)x centers at the active sites of the [FeFe]-hydrogenase enzymes. The most useful synthetic route to Fe2(μ-SR)2(CO)6 involves the reaction of thiols with Fe2(CO)9 and Fe3(CO)12. Such reactions can proceed via mono-, di-, and triiron intermediates. The reactivity of Fe(0) carbonyls toward thiols is highly chemoselective, and the resulting dithiolato complexes are fairly rugged. Thus, many complexes tolerate further synthetic elaboration directed at the organic substituents. A second major route involves alkylation of Fe2(μ-S2)(CO)6, Fe2(μ-SH)2(CO)6, and Li2Fe2(μ-S)2(CO)6. This approach is especially useful for azadithiolates Fe2[(μ-SCH2)2NR](CO)6. Elaborate complexes arise via addition of the FeSH group to electrophilic alkenes, alkynes, and carbonyls. Although the first example of Fe2(μ-SR)2(CO)6 was prepared from ferrous reagents, ferrous compounds are infrequently used, although the Fe(II)(SR)2 + Fe(0) condensation reaction is promising. Almost invariably low-yielding, the reaction of Fe3(CO)12, S8, and a variety of unsaturated substrates results in C–H activation, affording otherwise inaccessible derivatives. Thiones and related C═S-containing reagents are highly reactive toward Fe(0), often giving complexes derived from substituted methanedithiolates and C–H activation.

“…Our work in this area has resulted in the synthesis of several new ferrocenyl containing metal carbonyl cluster compounds. [9][10][11][12][13][14][15][16][17][18] Previously, we have also reported that the reaction of an eneyne system (isopropenyl acetylene) with [Fe(CO) 5 ] in the presence of CO, yields the products 2,6-and 2,5-divinyl-substituted 1,4-benzoquinone. 19 In continuation of our work in the chemistry of ene-yne and ferrocenyl groups as substituents, our main goal has been to explore the reactivity of the multifunctional organotellurium (tellurium ene-yne) ligand bearing ferrocenyl groups, (Z)-1-ferrocenyltelluro-1-ferrocenyl-4-ferrocenyl-1buten-3-yne, with metal carbonyls for the formation and expansion of metallic clusters.…”

The photolytic reaction of (Z)-1-ferrocenyltelluro-1-ferrocenyl-4-ferrocenyl-1-buten-3-yne with iron pentacarbonyl in hexane gives the tellurium coordinated carbonyl vinylallyl dinuclear iron complex 1, tellurium coordinated vinylallyl trinuclear iron complex 2, a lactone fused ferracyclopentadiene complex 3, and a butterfly complex 4. On reaction with PPh 3 , 1 undergoes fragmentation to yield a cyclopentadienone (7) and the starting material (Z)-1-ferrocenyltelluro-1-ferrocenyl-4-ferrocenyl-1buten-3-yne. In addition, reactions of the tellurium ene-yne ligand with [M(CO) 5 (THF)] or [M(CO) 6 ] give the M(CO) 5 adducts 8-10. All compounds have been characterized by IR, 1 H NMR and 13 C NMR spectroscopy and structures of 1-4 and 7 have been established by single crystal X-ray diffraction.
