摘要： 6,6-二烷基富烯与烯丙基氯化镁发生环外双键的加成反应,形成1,1-二烷基-3-丁烯基环戊二烯基氯化镁,同苯乙炔基钠则和6-位碳上甲基或亚甲基的c:-H反应,环外双键移位得到乙烯基环戊二烯基钠。这些阴离子与ⅣB族金属氯化物反应合成了一系列新的烯基取代环戊二烯基金属衍生物。

Abstract: 6,6-Dialkylfulvene reacts with allyl Grignard reagents to give addition products 1,1-dialkyl-3-butenylcyclopentadienyl magnesium chloride or bromide .When phenylacetylenic sodium is used instead of the Grignard reagent, the substituted fulvene forms substituted vinylcydopentadienyl sodium through a double bond shift. These substituted cyclopentadienyl anions react with metal chlorides of Ⅳ Bgroup to form a series of novel substituted metallocenes.

Key words: 6,6-Dialkylfulvene, Allyl Grignard reagents, Phenylacetylenic Sodi-um, Alkenylcyclopentadienyl Ⅳ B group metal derivatives
