| titleOfInvention | Method for producing metallocene compound |
| abstract | (57) [Summary] (Modified) [Configuration] Formulas (1) and (3) (R 1 , R 2 , R 3 and R 4 are C 1 -C 4 alkyl, trialkylsilyl, phenyl, hydrogen, R 1 , R 2 , R 3 , At least one R 4 may be a group different from each other, not hydrogen. Cp represents a 1,3-cyclopentadiene ring) and a substituted cyclopentadiene represented by the formula (3) is reacted with dimethyldihalosilane in the presence of a metal salt-type base and a metal ion trapping agent. Dimethyl bis (substituted cyclopentadienyl) silane is prepared, the silane is dissolved in a solvent and a strong base is added to prepare the product [A], while the transition metal halogen compound is dispersed in an inert solvent. Then, a complexing solution [B] obtained by dissolving or suspending in an ether solvent is prepared, and the product [A] and the complexing solution [B] are prepared. React with and formula (5) A silicon-bridged metallocene compound represented by is produced. [Effect] Decomposition and coagulation in the transition metal salt / solvent system solution formation are prevented, and the reaction time can be shortened, side reactions can be suppressed, and the yield can be improved. |
