Fluorine-containing cyclohexylbenzoic acid phenyl ester derivative

Abstract

Abstract NEW MATERIAL:A 4-(trans-4-substituted-cyclohexyl)-2-fluorobenzoic acid-4-cyanophenyl ester derivative shown by the formula I (R is 1-10C alkyl, or alkoxy). EXAMPLE:4-(trans-4-hexylcyclohexyl)-2-fluorobenzoic acid-4-cyanophenyl ester. USE:A liquid crystal display element substance. Having positive dielectric anisotropy and low viscosity. PREPARATION:3-Fluorobromobenzene shown by the formula II is reacted with magnesium, reacted with a 4-substituted cyclohexanone, and dehydrated. The resultant compound is catalytically reduced, reacted with acetyl chloride, oxidized further, and reacted with p-cyanophenol, to give a compound shown by the formula I .
