Abstract

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
