摘要
本文报道通过由Fe_3(CO)_(12)/RSH/Et_3N体系所形成的中间物[(μ-CO)(μ-RS)Fe_2(CO)_6]Et_3NH与Ph_2PCl,(p-CH_3C_6H_4)_2PCl或p-CH_3C_6H_4PCl_2反应,合成了7个蝶状Fe_2SP簇合物: (μ-Ph_2P)(μ-RS)·Fe_2(CO)_6(R=Pr^(?),Pr^(?),Bu^(?))、[μ-(p-CH_3C_6H_4)_2P](μ-Pr(?)S)Fe_2(CO)_6以及(μ-p-CH_3C_6H_4PCl)(μ-RS)Fe_2·(CO)_6(R=Et,Pr^(?),Bu^(?))。并对它们的~1H NMR、^(31)P NMR波谱与构象体的关系以及簇合物(μ-Ph_2P)(μ-Bu^(?)S)Fe_2(CO)_6的催化活性进行了初步探讨。
Seven butterfly-shaped Fe,SP cluster complexes: (μ-Ph2P)(μ-RS)Fe2(CO)6(R = Prn, Pri, But), [μ-(p-CH,C,H4)2P](μ-PriS)Fe2(CO), and (μ-p-CH,C,H,PCl) (μ-RS)Fe2(CO)6(R = Et, Pri, But) have been synthesized by the reaction of an intermediate [(μ-CO) (μ-RS)Fe,2(CO)6]Et3NH (formed from Fe3(CO)12, RSH and Et,N) with Ph2PCl, (p-CH3C6H4),PCl or p-CH3C4H4PCl2. For these new complexes the relationship between the 1H NMR, 31P NMR spectroscopic features and the possible conformers has been discussed. In addition, a kind of catalytic reactivity for the complex of (μ-Ph2P)(μ-ButS)Fe2(CO)6 has been investigated preliminarily.
