Abstract

NEW MATERIAL:An ester compound shown by the formula I (R and R' are 1W8C straight-chain alkyl).
EXAMPLE: (2'-Cyano-4'-n-butyl)phenyl-3-chloro-n-hexoxybenzoate.
USE: An additive for a liquid crystal composition having dielectric asisotropy. The addition of its small amount increases the dielectric, anisotropy of the liquid crystal composition in a high frequency range in the negative direction. The compound shown by the formula I has no liquid crystal properties. Being used as a display element of a guest host of a positive type, etc., it lowers a driving voltage and effective for the reduction of the consumption of electric power.
PROCESS: A compound shown by the formula II is chlorinated to give a compound shown by the formula III, which is alkylated to prepare a compound shown by the formula IV, which is converted with thionyl chloride to a compound shown by the formula V. While a compound shown by the formula VI. While a compound shown by the formula VI is brominated to give a compound shown by the formula VII, which is cyanized to prepare a compound shown by the formula VIII. This compound is esterified with the compound shown by the formula V to give the titled compound shown by the formula I.
