| titleOfInvention | Ether threshold value voltage-lowering agent |
| abstract | NEW MATERIAL:A compound of formula I [R is linear chain 1-5C alkyl; the cyclohexane ring has a trans (equatorial-equatorial) configuration; X is F or H]. n EXAMPLE: A compound of formula VIII. n USE: A threshold value voltage-lowering agent useful as a material for preparing liquid crystal display cells responding at high speeds and driven at low voltage, capable of lowering the viscosity of mixed liquid crystals and of effectively dropping the threshold value voltage and having excellent solubility in general mixed liquid crystals. n PREPARATION: A compound of formula II is reacted with methoxymethyl triphenyl phosphonium chloride and the resultant compound of formula III is treated with hydrochloric acid to prepare a compound of formula IV. The compound of formula IV is reacted with the above-mentioned chloride and the resultant compound of formula V is treated with hydrochloric acid to produce the compound of formula VI. The compound of formula VI is reacted with the avove-mentioned chloride to give the compound of formula VII, which is reduced in the presence of Raney nickel catalyst to provide the compound of formula I. n COPYRIGHT: (C)1991,JPO&Japio |
