Abstract
NEW MATERIAL:A compound of formulaI(R is 1W10C alkyl).
EXAMPLE: 3-[trans-4'-(trans-4"-Heptylcyclohexyl)cyclohexyl]chlorobenzene.
USE: Liquid crystal that has small positive dielectric anisotropy, low viscosity and a wide range of nematic temperature.
PREPARATION: The reaction of a compound of formula II with metallic magnesium gives a compound of formula III, which is made to react with a compound of formula IV to form a compound of formula V. The product is dehydrated in the presence of KHSO4 to give a compound of formula VI, which is reduced to a compound of formula VII. Further, this compound is recrystallized from ethanol to give the compound of formulaI.
