  公开（公告）日：2018-08-16

  The present invention provides a compound represented by General Formula (I). The compound according to the present invention prevents the liquid crystal composition from being deteriorated due to light, has high compatibility with the liquid crystal composition, and does not impair the storage stability of the liquid crystal composition, thus the compound is useful as a constituent member of a liquid crystal composition. Since the liquid crystal composition and the liquid crystal display element containing the compound of the present invention exhibit UV resistance and have a high VHR, it is possible to obtain a liquid crystal display element with excellent display quality in which display defects such as burn-in and display unevenness do not occur or are suppressed.

  本发明提供了一种由通式（I）表示的化合物。根据本发明的化合物可以防止液晶组合物因光照而恶化，与液晶组合物具有高兼容性，并不会损害液晶组合物的储存稳定性，因此该化合物作为液晶组合物的组成部分是有用的。由于含有本发明化合物的液晶组合物和液晶显示元件表现出UV抵抗性，并具有高VHR，因此可以获得具有优异显示质量的液晶显示元件，其中不会发生或被抑制烧屏和显示不均匀等显示缺陷。

• Reaction of Trialkylboranes with Cyclic α-Diazo Ketones. A New Synthesis of α-Alkyl Cycloalkanones
  作者：John Hooz、Donald M. Gunn、Hiromichi Kono

  DOI：10.1139/v71-385

  日期：1971.7.1

  An efficient procedure has been developed for the alkylation of cyclic ketones, based on the reaction of trialkylboranes with cyclic α-diazo ketones. The reaction proceeds under mild conditions, affords high yields of α-alkylated cycloalkanones, and circumvents certain difficulties inherent in previous alkylation methods.

  基于三烷基硼烷与环状 α-重氮酮的反应，已开发出一种用于环状酮烷基化的有效方法。该反应在温和的条件下进行，α-烷基化环烷酮的收率高，并避免了先前烷基化方法中固有的某些困难。
