Abstract
NEW MATERIAL:4-[trans-4'-(trans-4"-Alkylcyclohexyl)cyclohexyl]fluorobenzene.
USE: A liquid crystal with positive dielectric anisotropy: it has low viscosity, high clear point, and a wide range of nematic temperature. Further, the threshold voltage and saturation one rise little and it shows high stability to light, heat, air and water.
PREPARATION: 4'-(trans-4-Alkylcyclohexyl)cyclohexanol of formula II is oxidized with chromic anhydride to give a compound of formula III. In the meantime, magnesium is made to act on 4-bromofluorobenzene of formula IV to form the compound of formula V. Then, both products are made to react to give a compound of formula VI, which is dehydrated with potassium bisulfate to give a compound of formula VII. Further, the product is reduced to give a mixture of trans and cis isomers, finally recrystallization from ethanol is effected.
