[Et 3 NH] [（μ-CO）（μ-RS）Fe 2（CO）6 ]与烷基乙炔和芳基乙炔（R1 C = CR2）反应，生成（μ-σ，π-R1 C= CR2）（μ-RS）Fe 2（CO）6型中性μ-乙烯基配合物.据推测，这些产品的形成是由于在原位质子化的中间乙烯阴离子的三乙铵阳离子。1H NMR相关性表明，二铁和质子单元的整体加成以顺式方式发生
Reaction of [Et 3 NH] [(μ-CO) (μ-RS)Fe 2 (CO) 6 ] with alkyl- and arylacetylenes (R 1 C≡CR 2 ) produced neutral μ-vinyl complexes of the type (μ-σ, π-R 1 C=CHR 2 ) (μ-RS)Fe 2 (CO) 6 . Presumably, formation of these products resulted from the in situ protonation of an intermediate vinylic anion by the triethylammonium cation. 1 H NMR correlations have shown that overall addition of the diiron and proton units has occurred in a cis fashion
