研究了标题化合物[(Me~2Si)~n(C~5H~4)~2MCl~2, n=1,2,3;M=Ti, Zr, Hf]与酚的反应, 水解反应以及与卤素的相互置换反应。结果表明, 由于硅桥的不同它们表现出不同的反应活性。通过这些反应制备了十种新化合物, 用元素分析, 'H NMR 以及质谱鉴定了它们的结构。

关键词: 二茂铪, 氯化物, 二茂钛, 反应性, 硅桥, 金属茂络合物, 亲核试剂, 二茂锆

The reactions with phenols, hydrolysis, and halogen exchange reactions of the title compounds [[E(C5H4)2]MCl2] [E = (Me2Si)2, (Me2Si)3, Me2SiOSiMe2; M = Ti, Zr, Hf] were studied. The results showed that they revealed different reactivities due to variations of the silyl-bridge. Via these reactions 10 new compounds were prepared Their structures were characterized by elemental analyses, H NMR and mass spectra.

Key words: REACTIVITY, CHLORIDE, METALLOCENES, NUCLEOPHILIC REAGENTS
