Abstract

NEW MATERIAL:3-[trans-4'-(trans-4"-alkylcyclohexyl)cyclohexyl]fluorobenzene.
USE: A liquid crystal with a small positive dielectric anisotropy and low viscosity. This substance hardly crystallizes out to be helpful to improvement in display characteristics at low temperature. Further, it is used to expand the nematic temperature range.
PREPARATION: 4'-(trans-4-Alkylcyclohexyl)cyclohexanol of formula II is oxidized with chromic anhydride to give 4-(trans-4'-alkylcyclohexyl)cyclohexanone of formula III. In the meantime, the reaction between 3-bromofluorobenzene and metallic magnesium gives 4-fluorophenylmagnesium bromide and both produces are made to react to produce a compound of formula IV. The compound of formula IV is dehydrated to a compound of formula V, which is hydrogenated and recrystallized.
