摘要： 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、PhCH2Cl、ClCH2COOEt、I(CH2)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1HNMR谱表征了化合物的结构.

Abstract: 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 1H NMR measurements.

Key words: pentamethy disilany cyclopentadiene hexamethy trisiloxy bridged biscycl open-tadiene, molybdenum anion, alkylation reaction, oxidative coupling
