Abstract

NEW MATERIAL:An ester compound of formula I (R and R' are 1W8C staright chain alkyl groups).
EXAMPLE: 3-Cyano-4-n-pentyloxy-(2'-cyano-4'-n-pentylphenyl)benzoate.
USE: An additive for liquid crystals having the dielectric anisotropy, and capable of increasing the absolute value of the negative dielectric anisotropy of a composition at the low or high frequency region on addition in a small amount to the composition.
PROCESS: A compound of formula II is reacted with a compound of formula III to give a compound of formula IV, which is then reacted with cuprous cyanide to afford the compound of formula I. The compounds of formulas II and IV are obtained from compounds of formulas V and VI as starting materials respectively.
