| 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)TiCl2 and(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. |
