In a process for the preparation of ring compounds via a combinatorial synthesis, the reaction procedure is based on a Suzuki coupling, subsequent halo-demetallation and finally a further Suzuki coupling. The Suzuki couplings are each carried out with a boronic acid or a boronic acid ester. The reaction procedure uses provides novel ring compounds and uses novel synthesis units used for this purpose. The novel ring compounds are suitable for use as constituents in liquid-crystalline mixtures.
在通过组合合成制备环化合物的过程中,反应程序基于Suzuki偶联,随后进行卤去
金属化,最后再进行一次Suzuki偶联。Suzuki偶联分别使用
硼酸或
硼酸酯进行。该反应程序提供了新颖的环化合物,并使用了专为此目的设计的新颖合成单元。这些新颖的环化合物适用于作为液晶混合物中的组分。
