Abstract
NEW MATERIAL:A compound of formulaI(R1 is 1W10C alkyl; R2 is 1W10C alkyl or alkoxy).
EXAMPLE: 4-Methoxy-[trans-4'-(4"-heptylphenyl)cyclohexyl]benzene.
USE: A component of liquid crystal: it keeps liquid crystal phase over a wide range of temperature with low viscosity and high stability to heat, air, water and light and is used to make a liquid crystal composition working from low temperature to high one.
PREPARATION: 4-Alkyl-4'-hydroxyphenyl of formula II is hydrogenated and the product is made to react with metallic sodium to isolate a compound of formula III. The compound is oxidized to a compound of formula IV. In the meantime, the reaction between 4-substituted-bromobenzene and metallic magnesium gives a compound of formula IV. Then, the product is made to react with a compound of formula IV to give a compound of formula VII. The product is dehydrated, reduced and the resultant trans-mixture is recrystallized to give the compound of formulaI.
