Abstract
NEW MATERIAL:4'-Substituted-1'-cyclohexen-1'-yl-4-fluorobenzene of formula I (R is 1W10C alkyl or alkoxy).
EXAMPLE: 4'-Heptyl-1'-cyclohexen-1'-yl-4-fluorobenzene.
USE: Liquid crystal material for liquid crystal display element. Although the compound has low dielectric anisotropy, it has extremely low viscosity and low working voltage. Combined use of the material with other liquid crystal material gives a liquid crystal composition having remarkably improved characteristics.
PROCESS: Reaction of 4-fluorobromobenzene with magnesium in a solvent such as tetrahydrofuran gives 4-fluorobenzene magnesium bromide, which is then made to react with 4-substituted-cyclohexanone. The compound of formula I can be obtained by dehydrating the resulted 4'-substituted-1'-cyclohexanon-1'-ol-4-fluorobenzene of formula II with KHSO4.
