摘要: 烯丙基卤化镁和环戊二烯基溴化镁同6,6-二烷基富烯分别进行富烯环外双键的加成和还原反应,生成的取代环戊二烯基负离子用(CpTiCl2)2O(Cp=环戊二烯基)或TiCl4配合,合成通式为Cp(C5H1-CRR1-CH2CH=CH2)TiCl2和(C5H4CHRR1)2TiCl2的化合物。对烯丙基卤化镁、环戊二烯基溴化镁同富烯的反应机理进行了探讨。

Abstract: Exocyclic double bond addition and reduction took place when 6,6-dialkylfulvenes reacted with allylmagnesium halide and cyclopentadienyl magnesium bromide,respectively.Some titanium compounds Cp(C5H4)CRR1-CH2CH=CH2)TiCl2and(C5H4CHRR1)2TiCl2have been prepared by the complexation of substituted cyclopentadienyl anions obtained from the above reactions with(CpTiCl2)2O or TiCl4.However,no reaction was observed when 6,6-dialkylfulvenes were treated with ethylmagnesium bromide,n-butylmagnesium bromide,phenylmagnesium bromide,benzylmagnesium chloride, cyclopentadienyllithium and cyclopentadienylsodium,separately.Reaction mechanism of fulvenes with allylmagnesiumhalides and cyclopentadienylmagnesium bromide is discussed.
