| titleOfInvention | Trifluoromethyl compound |
| abstract | PURPOSE: To provide the title novel compound useful for liquid crystal compositions, high in K 3 /K 1 value, small in ▵ n value, excellent in compatibility having the ▵ε value positive, usable as STN-type display elements. n CONSTITUTION: The objective compound of formula I (R 1 is straight chain or branched 2-15C alkenyl; R 2 is straight chain or branched 1-15C alkyl; (n) is 1 or 2; (m) is 0 or 1), for example, 1-(4-trifluoromethyl) benzyloxy-2- allyl-4-(trans-4-propylcyclohexyl-trans-4-cyclohexyl) benzene. The present compound can be obtained, for example, by the following process: a ω- alkylallyloxyphenyl ether of formula II is put to Claisen rearrangement into an α-alkylallylphenol of formula III, which is, in turn, reacted with 4- trifluoromethylbenzyl bromide or 4-trifluoromethoxybenzyl bromide in the presence of anhydrous potassium carbonate. n COPYRIGHT: (C)1992,JPO&Japio |
