摘要: Wilkinson等[1]采用所谓经典的方法,制得二(甲基环戊二烯基)二氯化钛(Ⅰ),产率只有26%。Brantley[2]用TiCl4和相应的格氏试剂反摩也制得了该化合物,但操作条件较苛刻,产率未见报导。

Abstract: A novel method of synthesis of bis(methylcyclopentadienyl) titanium dichloride(Ⅰ) by reacting methylcyclopentadiene with titanium tetrachloride in the presence of diethylamine in tetrahydrofuran has been developed. Bis(methylcyclopentadienyl) titanium diphenoxide(Ⅱ) was synthesized and studied. Compound(Ⅱ) readily reacts with electrophilic reagents, such as hydrogen chloride, acetyl chloride and thionyl chloride, resulting in the cleavage of the oxygen-titanium bond and the formation of compound(Ⅰ).
