本文由Cp_2MCl_2和CP′_2MCl_2(CP=η~5-C_5H_5,CP′=η~5-CH_3C_5H_4,M=Ti,Zr,Hf)与芳基锂反应合成了一系列新的钛、锆、铪的双(环戊二烯基),双(甲基环戊二烯基)二芳基衍生物,研究了这些金属芳基衍生物的水解反应,锆和铪衍生物易发生水解,钛衍生物不易水解,它们与氯化氢、乙酰氯、溴和氢卤酸反应形成相应金属的双(环戊二烯基)二卤化物,文中还讨论了(η~5-CH_3C_5H_4)_2MAr_2和(η~5-CH_3C_5H_4)_2MX_2系列衍生物的核磁共振和红外光谱。
In this paper, a series of new titanium, zirconium and hafnium complexes have been synthesized by the reaction of Cp_2MCl_2 and CP’_2MCl_2 (CP = η ~ 5-C_5H_5, CP ’= η ~ 5-CH_3C_5H_4, M = Ti, Zr, Hf) Bis (cyclopentadienyl), bis (methylcyclopentadienyl) diaryl derivatives, the hydrolysis reaction of these metal aryl derivatives, zirconium and hafnium derivatives prone to hydrolysis, titanium derivatives is not easy Hydrolyzed, they react with hydrogen chloride, acetyl chloride, bromine and hydrohalic acid to form bis (cyclopentadienyl) dihalides of the corresponding metals. In addition, (η ~ 5-CH_3C_5H_4) _2MAr_2 and (η ~ 5-CH_3C_5H_4 ) _2MX_2 series of nuclear magnetic resonance and infrared spectroscopy.
