Studies on the Readions of Iron Carbonyl-Mercaptan(Thiophenol)Grignard Reagent System with Benzoyl Chlorides──Syntheses and Structures of Some Substituted μ- Benzoyl Fe/S Complexes

通过Ｆｅ３（ＣＯ）（１２）、硫醇（硫酚）和ＥｔＭｇＢｒ所形成的络盐［（μ－ＣＯ）（μ－ＲＳ）Ｆｅ２（ＣＯ）６］－Ｍｇ＋Ｂｒ与氯代芳酰氯的原位反应，合成了通式为（μ－ＲＳ）（μ－ｏ－ＣｌＣ６Ｈ４ＣＯ）Ｆｅ２（ＣＯ）６和（μ－ＲＳ）（μ－ｍ－ＣｌＣ６Ｈ４ＣＯ）Ｆｅ２（ＣＯ）６（Ｒ＝ｎ－Ｒｕ，ｔ－Ｂｕ，Ｐｈ）的６个新桥芳酰基铁硫配合物，并用Ｃ／Ｈ分析、ＩＲ和１ＨＮＭＲ表征了它们的结构。

The in situ reactions of the active complex salts [(μ-CO)(μ- RS)Fe2( CO) 6]-·Mg+Br,formed from triiron dodecacarbonyl,mercaptan or thiophenol and Grignard reagent EtMgBr,with o-or m-chlorobenzoyl chloride in THF at room temperature gave six new substituted μ-benzoyl Fe/S complexes with general formulas of(μ-RS) (μ-o-ClC6 H4 CO) Fe2( CO) 6 and( μ- RS)(μ-m-ClC6 H4 CO) Fez(CO)6(R=n-Bu,t-Bu,Ph),which were fully characterized by C/H analysis, IR and 1H NMR spectroscopy.
