摘要： 对一类新型阴离子络盐M+[(μ-CO)(μ-RS)Fe2(CO)6]-(M+=Et3NH+,Li+,Na+,MgX+)的合成、结构和反应进行了综述。该类络盐可由硫醇或硫酚盐RS-M+与Fe3(CO)12在THF中合成并于原位(insitu)反应。经单晶X射线衍射分析证实其阴离子中的Fe2SC骨架具蝶状结构,它显示高度的亲核反应活性,能同多种亲电底物反应。典型的底物包括卤代不饱和烃、酰氯、炔烃、磷、砷卤代物、二硫化碳、二氯化二硫、单质硫或硒及烃基卤化汞等。该类络盐业已成为一种有效试剂,它在新颖金属有机和原子簇化合物的合成中具有广泛的应用价值。

Abstract: The synthesis, structure and reactions of the new type of butterfly-shaped anioniccomplex salts M+[μ-CO) (μ-RS)Fe2(CO)6]-(M+=Et3NH+,Li+,Na+,MgX+) have beenreviewed.The complex salts were usually prepared by the action of alkanethiolates orarenethiolates RS-M+ on Fe3(CO)12 in THFand used in situ for subsequent reactions.Thesingle-crystal X-ray diffraction analysis confirmed that this kind of compsplex salts had a butterfly-shaped framework consisting of Fe2SCatoms.The complex salts are highly reactivetowards diverse electrophilic substrates.Such substrates, generally, include unsaturatedalkyl halides,acid chlorides,alkynes,halides of phosphorus and arsenic,carbon disulfide,sulfur(1) chloride, elemental sulfur and selenium and alkylmercuric chlorides etc..Apparently,such a kind of anionic complex salts has become a very effective reagent and has beenused extensively in the syntheses of novel organometallic and cluster complexes.
