通过(μ-巯基)(μ-烃硫)六碳基二铁与酰卤的亲核取代反应,合成了通式为(μ-CH3COS)(μ-RS)Fe2(CO)6的九个铁硫原子簇络合物.经元素分析, IR及^1H NMR光谱证实了所有这些络合物的结构和构象. 并简要地讨论了酰氯的反应活性及三乙胺在反应中的作用.

(m-AcS)(m-RS)Fe2(CO)6 (R = Me, Et, Pr, iso-Pr, tert-Bu, Ph, PhCH2, CH2:CHCH2, cyclohexyl) were prepared through nucleophilic substitution of (m-HS)(m-RS)Fe2(CO)6 with acid halides. The structures and conformers of all these complexes were confirmed by elemental anal., IR and 1H NMR spectroscopy. The reactivity of acid chlorides and the function of Et3N in the reaction are briefly discussed.
