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Ti Cl4、Zr Cl4反应 ,合成了一系列新的取代茂钛、锆化合物。
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 Ti Cl4and Zr Cl4.
