  Synthesis and Properties of Novel Liquid Crystalline Compounds having a Difluoromethyleneoxy Moiety as a Linkage Group

  摘要：

  Novel liquid crystal compounds having a difluoromethyleneoxy group as a linkage group have been prepared by the new synthetic method using dibromo-difluoromethane in good yield. From. the results of physical property measurements; i.e., transition temperature, dielectric anisotropy (Deltaepsilon), birefringence (Deltan) and viscosity, it becomes obvious that the derivatives having 3,5-Difluorophenyl group at the carbon side of difluoramethyleneoxy group ((1) under bar) have high dielectric anisotropy and low viscosity, and the derivatives having 1, 4-cyclohexylene group at the carbon side of difluoromethyleneoxy group ((2) under bar) have good balance of their physical properties. Moreover, (1) under bar and (2) under bar indicate high voltage holding ratio. Therefore, a novel series of the compounds having a difluoromethyleneoxy linkage group is an eminently suitable material that can lower driving voltage and achieve quicker response time of the AM-LCDs.

  An object of the present invention is to provide a method for producing a compound having an oxydifluoromethylene skeleton at a high yield by a simple process without using highly toxic starting materials, such as dibromodifluoromethane, while generating almost no difficult-to-separate impurities. A reaction between a thionocarboxylic acid ester (which may be obtained by a reaction between a halogenated thiocarbonyl compound and a specific compound as required) and a compound represented by Formula: XFn (wherein X represents chlorine, bromine, or iodine, and n represents a natural number of 1 to 5) gives a compound having an oxydifluoromethylene skeleton at a high yield. Various groups, such as an aromatic ring group, may also be introduced in high yield by reacting this compound with a boronic acid compound and the like as required.

  本发明的目的是提供一种方法，通过简单的工艺，在不使用剧毒起始原料（如二溴二氟甲烷）的情况下，高产率地生产具有氧二氟亚甲基骨架的化合物，同时几乎不产生难以分离的杂质。硫代羧酸酯（可根据需要通过卤代硫羰基化合物与特定化合物的反应获得）与由式：XFn（其中 X 代表氯、溴或碘，n 代表 1 至 5 的自然数）可得到具有氧二氟甲基骨架的高产率化合物。还可以根据需要，通过使该化合物与硼酸化合物等反应，高产率地引入各种基团，如芳香环基团。
