Abstract
NEW MATERIAL:A 4-[4'-(trans-4"-alkylcyclohexyl)cyclohexen-1'-yl]chlorobenzene expressed by formulaI(R is 1W10C alkyl).
EXAMPLE: 4-[4'-(trans-4"-Propylcyclohexyl)cyclohexen-1'-yl]chlorobenzene.
USE: A component of a liquid crystal composition, having a low viscosity, a wide nematic liquid crystal temperature range and the positive dielectric anisotropy.
PROCESS: 4-Bromochlorobenzene is reacted with Mg to give 4-chlorobenzenemagnesium bromide, which is then reacted with a 4-(trans-4'-alkylcyclohexyl)cyclohexanone expressed by formula II to afford a 4-[4'-(trans-4"-alkylcyclohexyl) cyclohexan-1'-ol]chlorobenzene expressed by formula III. The resultant compound is then dehydrogenated in the presence of potassium hydrogensulfide catalyst to give the aimed compound expressed by formulaI.
