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.
