二茚基钐断裂I—I,O—O和S—S键反应的研究

Studies on the I I O O S S Bond Break Reaction with Indenyl Samarium

通过２价Ｓｍ（Ｃ９Ｈ７）２与Ｉ２，（Ｃ６Ｈ５ＣＯ２）２，［（Ｃ２Ｈ５）２ＮＣＳ２］２作用，研究了在四氢呋喃溶液中Ｓｍ（Ｃ９Ｈ７）２断裂Ｉ－Ｉ，Ｏ－Ｏ，Ｓ－Ｓ键的反应，得到了３个新的、对空气和湿气敏感的３价稀土金属有机配合物．产物经元素分析、红外光谱、质谱等鉴定，推测其组成结构分别为（Ｃ９Ｈ７）２ＳｍＩ（ＴＨＦ）（Ａ）、［（Ｃ９Ｈ７）２Ｓｍ（（Ｃ６Ｈ５ＣＯ２）］２（Ｂ），｛（Ｃ９Ｈ７）２Ｓｍ［（Ｃ２Ｈ５）２ＮＣＳ２］｝２（Ｃ）．

Through the reactions of Sm(C 9H 7) 2 with I 2,(C 6H 5CO 2) 2 and [(C 2H 5) 2NCS 2] 2 to study I I,O O,S S break reactions with Sm(C 9H 7) 2 in THF produce three unreported,extremely air and moisture sensitive Sm(Ⅲ) organometallic complexes,namely:(C 9H 7) 2 SmI(THF)(A),[(C 9H 7) 2 Sm(C 6H 5CO 2)] 2(B),{(C 9H 7) 2 Sm[(C 2H 5) 2 NCS 2]} 2(C) have been obtained respectively. All the complexes were verified by element analysis,IR and MS spectra.
