摘要： 2,2′二溴联苯衍生物与正丁基锂发生溴-锂交换反应,生成的二锂化合物与二氯二茂钛、二氯二(甲基环戊二烯基)钛或二氯二茚钛作用,得到9种新的有机钛。芴进行了结构测定,并研究了5,5-二茂钛茚的反应性能。

Abstract: Nine new organic titana-fluorenes were synthesized by the reaction of 2,2′-dilithio-biphenyl (Prepared by lithiation of 2,2′-dibromobiphenyl with n-butyllithium) with dichlorodicyclopentadienyl titanium, dichlorodi (methyl-cyclopendienyl) titanium or dichlorodiindenyl titanium. They were separated by chromatography on silica. Their structures have been characterized by elemental analyses, IRspectra, 1HNMRand UVspectra. The reactions of 5,5-dicyclopenta-dienyl titana-fluorene with electrophilic reagents, such as HCl, HBr, SOCl2,I2 and (PhCOO)2, were studied.

Key words: Dicyclopentadienyl titanium derivatives, Organic titana-fluorenes, Syntheses
