本文报导了用聚氧乙烯类表面活性剂作为相转移催化剂,以环戊二烯与卤代烷反应合成烷基取代环戊二烯的方法。反应在固-液相条件下进行,其难易程度取决于卤代垸的反应活性。以该法合成了九个烷基取代环戊二烯衍生物。 This paper reports the synthesis of alkyl-substituted cyclopentadienes by the reaction of cyclopentadiene and alkyl halides using polyoxyethylene surfactants as phase transfer catalysts. The reaction is carried out under solid-liquid conditions, the ease of which depends on the reactivity of the halogenated embankment. Nine alkyl-substituted cyclopentadienyl derivatives were synthesized by this method.
