Abstract
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.
