摘要: 本文合成了(μ-PhS)(μ-RS)Fe2(CO)6系列的九个铁硫原子簇络合物,考察并确定了RX的结构对亲核取代反应活性的影响及络合物可能的空间异构体和比例.对由C≡O各向异性效应及硫上孤电子对的空间取向所引起的异构体中SCH3、SCH2δ值的规律变化进行了初步讨论.

Abstract: Through reductive addition of phLi to μ-S2Fe2(CO)6 and nucleophilic substitution between RXand (μ-PhS)(μ-LiS)Fe2(CO)6 nine clusters of (μ-PhS)(μ-RS)Fe2(CO)6 series (Ⅰ) -(Ⅸ) have been synthesized successfully.It is shown that yields of clusters (Ⅰ) -(Ⅸ) and reactivities of RXin nucleophilic reactions depend on both structures of Rand nature of X.And according to chemical shift and integrated values of related signals of 1HNMRpossible isomers and isomcr ratios of some clusters have been determined.In addition, it is suggested that diamagnetic aniso-tropic effects of C = Oand orientations of unshared electron pairs are likely responsible for systematic variations in δ CH3-Sand δ CH2-Sof cluster isomers.
