Abstract
NEW MATERIAL:The carboxylic acid 3-chloro-4-cyanophenyl ester of formulaI (R is 1W10C alkyl or alkoxy; the rings A and B are benzene ring or cyclohexane ring).
EXAMPLE: 4-(trans-4'-propylcyclohexyl) benzoic acid 3"-chloro-4"-cyanopheyl ester.
USE: A liquid crystal compound having large positive dielectric anisotropy. Its dielectric anisotropy is as high as about +30, and the compound exhibits liquid crystal phase over a wide temperature range.
PROCESS: The compound of formulaIis prepared by converting the substituted carboxylic acid of formula II having a structure corresponding to the final objective compound to the substituted carboxylic acid chloride of formula III with SOCl2, etc., and reacting with 3-chloro-4-cyanophenol of formula IV in the presence of pyridine.
