双环戊二烯基二芳氧基钛的酸解反应

ACIDOLYSIS REACTIONS OF BIS(CYCLOPEN-TADIENYL)-DI-(ARYLOXY)-TITANIUM

本文研究了双环戊二烯基二芳氧基钛于氢卤酸中的酸解反应。证明反应是分步进行的。因反应条件不同可得到二次酸解产物——双环戊二烯基二卤化钛或一次酸解产物——双环戊二烯基芳氧基卤化钛。对影响反应的诸因素进行了讨论。通过上述酸解反应合成了一系列新的双环戊二烯基芳氧基卤化钛,收率较高。由双环戊二烯基芳氧基卤化钛开始,又合成了几个新的Cp_(2)Ti(OAr)Ar'及Cp_(2)Ti(OAr)(OAr')类型衍生物。

Acidolysis reactions of bis-(cyclopentadienyl)-di-(aryloxy)-titanium were studied.It was proved that acidolysis reactions go step by step.According to the reaction conditions,the second-step acidolysis product,bis-(cyclopentadienyl)-titanium dihalides,and the first-step acidolysis product,bis-(cyclopentadienyl)-(aryloxy)-titanium halides,were obtained.Reaction conditions were discussed.Through above-mentioned reactions,a series of new bis-(cyclopentadi nyl)-(aryloxy)-titanium halides have been synthesized with good yields.Starting from bis-(cyclopentadienyl)-(aryloxy)-titanium halides,a few new derivatives with formulae Cp_(2)Ti(OAr)Ar and Cp_(3)Ti(OAr)(OAr’)have prepared.
