Synthesis and Characterization of Tricarbonylhexamethylsilylcyclopentadienyl Molybdenum Derivatives

通过三羰基（五甲基二硅基）环戊二烯基钼负离子盐与卤代烃（ＥｔＩ、ＰｈＣ＿（２）Ｃｌ、ＣｌＣＨ＿（２）ＣＯＯＥｔ、Ｉ（ＣＨ＿２）＿４Ｉ）进行烷基化反应合成其烷基钼化合物．用六甲基三硅二氧烷桥联双（三羰基环戊二锑基钼）负离子经冰醋酸处理、硫酸铁氧化偶联成钼－钼键双核化合物，经碘裂解后钼－钼键生成六甲基三硅二氧烷桥联双（三羰基环戊二烯基碘钼）比合物。以元素分析、ＩＲ和￣（１）ＨＮＭＲ谱表征了化合物的结构．

The alkyl-molybdenum compounds were synthesized via reactions of tricar-bonylpentamethyldisilanyicyclopentadienyl molybdenum anion saIt with alkyl halide(ethyl-chloroacetate,benzyl chloride,ethyliodide,1,4-diiodobutane).The hexamethyltrisiloxyl-bridged-bis(tricarbonylcyclopentadienyl molybdenum anion salt)was treated with glacialacetic acid and followed reacted with ferric sulfate to produce the oxidative coupling molybd-num-molybdenum dinuclear compound.HexamethyItrisiloxyl-bridged bis(tricarbonyl-cyclopentadienyliodo-molybdenum)compound was formed by cleavage of molybdenum-molybdenum bond with iodine. The structures of title compounds were characterized by ele-mental analysis,IR and ￣(1)H NMR measurements.
