A process is disclosed for preparing 2-aryl-substituted indenes by reacting an indene with an arene compound substituted with an halogen atom, preferably a iodine atom, or with an organosulphonate group, said reaction being carried out in a basic medium in the presence of a palladium catalyst. The compounds obtainable by this process can be used to prepare metallocene compounds with transition metals such as titanium, zirconium or hafnium, which are useful as catalyst components in the polymerization of olefins.
本发明公开了一种制备2-芳基取代茚烯的方法,包括将一种含有卤素原子(优选碘原子)或有机磺酸盐基团的芳香化合物与茚烯反应,在碱性介质中存在钯催化剂。通过该方法可获得的化合物可用于制备与过渡金属(如钛、锆或铪)形成的金属茂化合物,这些金属茂化合物可用作聚烯烃催化剂组分。
