Abstract
NEW MATERIAL:The carboxylic acid pentafluorophenol ester of formulaI[Z is group of formulaIWformula VII (R is is 1W15C alkyl or alkoxy)].
EXAMPLE: trans-4-(trans-4'-Ethylcylohexyl)cyclohexanecarboxylic acid pentafluorophenyl ester.
USE: A component of a liquid crystal composition having small positive dielectric anisotropy and low viscosity.
PROCESS: The compound of formulaIis prepared by converting the carboxylic acid derivative corresponding to the objective compound to the acid chloride with thionyl chloride, and reacting with pentafluorophenol in the presence of pyridine.
