“…In recent years the chemical reactions of diiron complex salts [Et 3 NH][(μ-RS)(μ-CO)Fe 2 (CO) 6 ] ( 1 ) have been intensively studied and widely utilized in the synthesis of organometallic compounds and particularly organometallic clusters. − Among the reactions studied were those with electrophiles that have no leaving group such as acetylenes and elemental sulfur. , As part of our project concerning the chemistry of the anions [(μ-RE)(μ-CO)Fe 2 (CO) 6 ] - (E = S, Se, Te), − we recently carried out an investigation on the reactions of 1 with the inorganic acetylene analogues [(η 5 -R‘C 5 H 4 )(CO) 2 M] 2 ( 2 , M = Mo, W) followed by treatment with air. Consequently, these reactions afforded a series of novel thiolato-bridged, oxo-capped trimetallic clusters (η 5 -R‘C 5 H 4 )(CO) 2 MFe 2 (μ 3 -O)(μ-RS)(CO) 6 ( 3a − k ), as described below.…”

Synthesis of Double and Quadruple Butterfly Fe/E Cluster Complexes via a New Type of Selenium-Centered Anions (μ-RE)(μ-Se-)[Fe2(CO)6]2(μ4-Se) (E = S, Se, Te) Derived from Novel Reaction of [(μ-RE)(μ-CO)[Fe2(CO)6]- with (μ-Se2)Fe2(CO)6.

“…The μ -CO-bridged anions of type [( μ -RE)( μ -CO)Fe 2 (CO) 6 ] - ( 1 , E = S, Se, Te) are rich in chemical reactivities and have been extensively used as an important class of synthon to synthesize a variety of novel cluster complexes. − In previous papers 18-20 we reported that anions 1 reacted with ( μ -S 2 )Fe 2 (CO) 6 in THF at room temperature (for E = S) or from −78 °C to room temperature (for E = Se, Te) to give a new type of butterfly Fe/E cluster sulfur-centered anions ( μ -RE)( μ -S - )[Fe 2 (CO) 6 ] 2 ( μ 4 -S) ( 2 ) (Scheme ).

Novel Reaction of Complex Salts [(μ-RE)(μ-CO)Fe2(CO)6][HNEt3] (E = S, Se) with Phosphaalkene t-Bu(Me3SiO)CPSiMe3. Synthesis and Spectroscopic and Crystallographic Characterization of Butterfly Fe2EP Clusters (μ-RE)[μ-t-Bu(Me3SiO)CHPH]Fe2(CO)6 (E = S, Se)

“…In recent years the complex salts [(μ-RE)(μ-CO)Fe 2 (CO) 6 ][HNEt 3 ] ( 1 , E = S, Se) have been intensively studied and successfully utilized in the synthesis of Fe−E cluster complexes containing a great variety of organic and inorganic bridging groups. − Furthermore, the compounds containing phosphorus−carbon multiple bonds, such as phosphaalkyne t-BuC⋮P and phosphaalkene t-Bu(Me 3 SiO)CPSiMe 3 , have also been extensively studied and up to now have become important synthons for phosphorus-containing organic and organometallic compounds. However, to our knowledge, only one example is so far reported concerning the reaction of complex salts 1 with the compounds containing phosphorus−carbon multipe bonds, in which the E atom of complex salts 1 is sulfur and the phosphorus compound is a phosphaalkene .…”
