摘要： 二(甲基环戊二烯基)二氯化钛[(MeCp)2TiCl2](Ⅰ),Wilkinson等人[1]曾用四氯化钛和甲基环戊二烯基钠反应来制备,产率26％.后来Brantly[2]用四氯化钛和MeC5H4MgCl在乙醚-苯混合溶液中于-70℃反应.以上两种方法不但操作复杂,且条件苛刻,产率低.最近吴绍祖等[3]用二乙胺作为氯化氢的接受体,四氢呋喃作溶剂,由TiCl4和甲基环戊二烯直接反应来合成.产率43％.我们采用甲基环戊二烯基锂与TiCl4反应来合成,产率为63％.

Abstract: In this paper, the bis(methyl-cyclopentadienyl) titanium dichloride is prepared by means of reaction of methyl-cyclopentadienyl lithium with titanium tetrachloride. Some new dimethylcyclopentadienyl compounds of titanium such as (MeCp)2Ti (OR)2 and (MeCp)2Ti (OR') Cl (R = C6H3Me2-2,4, C6H4NO2-3, C6H4NO2-4; R' = C6H3Me2-3,5) have also been synthesized. Their IR and 1HNMR spectra are given.
