| 摘要: 研究了正庚基锂、正辛基锂同6,6-二烷基富烯反应的立体和溶剂效应对反应类型的影响。在弱极性溶剂中(方法A,B),正庚基锂、正辛基锂同6,6-二烷基富烯主要发生加成反应;在极性溶剂中(方法C),则倾向于加成和还原两种反应。利用上述反应形成的环戊二烯基阴离子同TiCl4、ZrCl4反应,合成了一系列新的取代茂钛、锆化合物。 |

| Abstract: The steric and solvent effects on reaction types of 6,6-dialkylfulvenes and 6,6-polymethylenefulvenes with n-heptyllithium and n-octyllithium were investigated.Addition, reduction andα-hydrogen abstraction took place competitively when6,6-dialkylfulvenes and 6,6-polymethylenefulvenes reacted with n-heptyllithium and n-octyllithium in three different solvents,respectively.A series of novel substituted titanocenesand zirconocenes compounds have been prepared by complexation of cyclopentadienyl anions obtained in the above reactions with TiCl4 and ZrCl4. |
| Keywords: n-heptyllithium n-octyllithium fulvene substituted metallocene compound |
