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_2Ti(OAr)Ar＇及Cp_2Ti(OAr)(OAr＇)类型衍生物。
In this paper, the acid hydrolysis of dicyclopentadienyl diaryloxide in hydrohalic acid was studied. Prove the reaction is a step-by-step. Depending on the reaction conditions, the second acid-hydrolyzate, dicyclopentadienyltitanium dihalide or primary acid-hydrolyzate, biscyclopentadienylaryl halide, can be obtained. The factors that influence the response are discussed. A series of new dicyclopentadienyl aryl oxyhalides were synthesized by the above acid hydrolysis reaction with high yield. Starting from dicyclopentadienyl aryl-oxyhalides, several new derivatives of Cp_2Ti (OAr) Ar ’and Cp_2Ti (OAr) (OAr’) have also been synthesized.
