    • A process for preparing boratabenzene derivatives is provided. The process includes the hydrogenation of a compound containing a boranaphthalene functional group to form a boratabenzene-containing compound. Depending on the compound containing a boranaphthalene functional group, the resulting boratabenzene compound may be converted into a catalyst suitable for olefin polymerization. A process for forming a boratabenzene derivative from a halo-dioxaborolane is also provided. In this process, a halo-dioxaborolane is reacted with a piperylide salt for form a pentadienyl dioxaborolane. The pentadienyl-dioxaborolane is reacted with a strong base to form an intermediate boratacyclohexanediene salt. The intermediate boratacyclohexanediene salt is then reacted with a trialkylaluminum compound to form an alkylboratabenzene salt.
    • 提供了一种制备硼代苯衍生物的方法。 该方法包括含有硼烷官能团的化合物的氢化以形成含硼代苯的化合物。 根据含有硼烷官能团的化合物,所得的硼代苯化合物可以转化为适用于烯烃聚合的催化剂。 还提供了由卤代二氧硼烷制备硼代苯衍生物的方法。 在该方法中,将卤代二氧杂硼杂环戊烷与哌啶子盐反应形成戊二烯基二氧杂硼杂环戊烷。 将戊二烯基二氧杂硼杂环戊烷与强碱反应形成中间体硼烷环己烷二盐。 然后将中间体硼烷环己二烯盐与三烷基铝化合物反应以形成烷基硼代苯盐。
