苯二甲酰基桥联铁硫配合物［（μ－RS）Fe_2（CO）_6］_2（μ－OCC_6

Synthesis and Characterization of Phthaloyl Bridged Iron-Sulfur Complexes [(μ-RS)Fe2(CO)6]2(μ-OCC6H4CO-μ)

通过由Ｆｅ３（ＣＯ）１２、ＲＳＨ和Ｅｔ３Ｎ所形成的［（μ－ＣＯ）（μ－ＲＳ）Ｆｅ２（ＣＯ）６］Ｅｔ３ＮＨ于室温下分别与对或间苯二甲酰氯的原位反应，首次合成６个结构新颖的苯二甲酰基桥联铁硫配合物［（μ－ＲＳ）·Ｆｅ２（ＣＯ）６］２（μ－ｐ－ＯＣＣ６Ｈ４ＣＯ－ｐ－μ）（Ｒ＝Ｅｔ，ｎ－Ｂｕ，ｔ－Ｂｕ）以及［（μ－ＲＳ）Ｆｅ２（ＣＯ）６］２（μ－ｍ－ＯＣＣ６Ｈ４ＣＯ－ｍ－μ）（Ｒ＝ｎ－Ｐｒ，ｎ－Ｂｕ，ｔ－Ｂｕ）。经元素分析、ＩＲ光谱及１ＨＮＭＲ表征了它们的结构，并讨论了产物的生成过程。此外，还提出了合成对苯二甲酰氯的一种新方法。

The in situ reaction of the complex salts [(μ-CO)(μ-RS)Fe2(CO)6]Et3NH derived from Fe3(CO)(12),RSH and Et3N with p-,or m-phthaloyl chloride in THF at room temperature afforded six novel phthaloyl bridged iron-sulfur complexes [(μ-RS)Fe2(CO)6]2(μ-pOCC6H4CO-p-μ)(R=Et,n-Bu, t-Bu) and [(μ-RS)Fe2(CO)6]2(μ-m-OCC6H4CO-mμ)(R=n-Pr,n-Bu,t-Bu).These new complexes were characterized by elemental analysis,IR and 1H NMR spectroscopies and the reaction course was discussed.In addition,a new synthetic route to p-phthaloyl chloride has been developed.
