Abstract

NEW MATERIAL:A compound expressed by formulaI(R is 1W10C alkyl).
EXAMPLE: 3,4-Difluoro-4'-(trans-4"-propylcylohexyl)biphenyl.
USE: A liquid crystal display element, exhibiting the liquid crystal phase at a temperature in the range of about 60W100°C and having a low viscosity. Although the dielectric anisotropy is +4, the threshold voltage and saturation voltage of a liquid crystal composition containing the compound expressed by formulaIare equal or reduced.
PROCESS: 1-Bromo-3, 4-difluorobenzene is reacted with Mg to give 3, 4-difluorophenyl magnesium bromide, which is then reacted with a compound expressed by formula II to afford a compound expressed by formula III. The resultant compound expressed by formula III is then dehydrated with potassium hydrogensulfate to give a compound expressed by formula IV, which is finally dehydrogenated with chloranil to afford the compound expressed by formulaI.
