本文表明(μ-RS)(μ-XMgS)Fe_2(CO)_6(R=Me,X=I;R=Et,X=Br)或(μ-LiS)_2Fe_2(CO)_6能顺利地对环氧乙烷、环氧氯丙烷进行亲核开环反应,且开环中间物经原位(in situ)醇解生成四新β-羟乙基铁硫配合物:(μ-CH_3S)〔μ-ClCH_2CH(OH)CH_2S〕Fe_2(CO)_61,(μ-C_2H_5S)(μ-HOCH_2CH_2S)Fe_2(CO)_62,(μ-HOCH_2CH_2S)_2Fe_2(CO)_64,[μ-ClCH_2CH(OH)CH_2S]_2Fe_2(CO)_65.配合物1的结构由元素分析、IR和~1HNMR直接证实,配合物2、4、5的结构是由鉴定其三苯膦衍生物而间接得到证实。本文还对环氧氯丙烷的开环方向进行了简要讨论。
In this paper, we show that (μ-RS) (μ-XMgS) Fe_2 (CO) _6 (R = Me, X = I; R = Et, X = Br) Ethylene oxide, epichlorohydrin nucleophilic ring-opening reaction, and the ring-opened intermediate by in situ alcoholysis to generate four new β-hydroxyethyl iron sulfur complex: (μ-CH_3S) 〔μ- (Μ-HOCH_2CH_2S) Fe_2 (CO) _62, (μ-HOCH_2CH_2S) _2Fe_2 (CO) _64, [μ-ClCH_2CH (OH) CH_2S] _2Fe_2 (CO) CO) _65. The structure of complex 1 was confirmed by elemental analysis, IR and ~ 1HNMR. The structures of complexes 2,4,5 were confirmed indirectly by the identification of their triphenylphosphine derivatives. This article also briefly discusses the ring-opening direction of epichlorohydrin.
