  The nematic liquid crystal composition according to the present invention is used for, for example, producing a liquid crystal display elementused in TN mode, OCBmode, ECBmode, IPSmode, or VA-IPS mode. The liquid crystal composition has a positive dielectric anisotropy and allows reductions in refractive-index anisotropy and nematic phase-isotropic liquid phase transition temperature and an increase in the lower limit temperature of a nematic phase to be suppressed. As a result, the liquid crystal composition has a sufficiently low viscosity without deteriorating the temperature range of a nematic phase. The liquid crystal composition allows high-speed response and high display quality to be realized, suppresses faulty display, and is suitably used as a practical liquid crystal composition.

  本发明的向列液晶组合物可用于生产 TN 模式、OCB 模式、ECB 模式、IPS 模式或 VA-IPS 模式的液晶显示元件。液晶组合物具有正的介电各向异性，可抑制折射率各向异性和向列相-各向异性液相转变温度的降低以及向列相下限温度的升高。因此，液晶组合物具有足够低的粘度，同时不会恶化向列相的温度范围。该液晶组合物可实现高速响应和高显示质量，抑制故障显示，适合用作实用液晶组合物。

  On the basis of the reaction of ethynediylbisphosphonates and chloroethynylphosphonates with classical donor alka-1,3-dienes, a general strategy for synthesis of o-bisphosphanylbenzenes and o-chlorophosphanylbenzenes, which includes two consecutive steps: Diels-Alder condensation -> aromatization of the carbocyclic phosphonate (bisphosphonate) formed -> reduction of the phosphonate groups, was developed. Convenient procedures are devised for aromatization of phosphorus-containing cyclohexa-1,4-dienes and for reduction of o-phenylenebisphosphonates and o-clorophenylphosphonates to primary phosphines. A series of new alkylsubstituted phosphonic chlorides were prepared, and a possibility of functionalization of methyl-substituted o-phenylenebisphosphonates and o-clorophenylphosphonates by the methyl groups is demonstrated.
