Abstract
NEW MATERIAL:A 4-[trans-4'-(alkylcyclohexyl)cyclohexyl]chlorobenzene expressed by formulaI (R is 1W10C alkyl).
EXAMPLE: 4-[trans-4'-(trans-4"-Propylcyclohexyl)cyclohexyl]chlorobenzene.
USE: A component of a liquid crystal composition, having a low viscosity, wide nematic liquid crystal temperature range and the positive dielectric anisotropy.
PROCESS: 4-Chlorobenzenemagnesium bromide obtained from 4-bromochlorobenzene is reacted with a 4-(trans-4'-alkylcyclohexyl)cyclohexanone expressed by formula II to give a compound expressed by formula III, which is then dehydrogenated in the presence of potassium hydrogensulfate as a catalyst to afford a compound expressed by formula IV. The resultant compound expressed by formula IV is then reduced in the presence of a platinum oxide catalyst to afford the compound expressed by formulaI.
