| titleOfInvention | Branched phenylpyrimidine compound and liquid crystal composition containing the same |
| abstract | NEW MATERIAL:A compound of formula I (X and Y are each H or methyl, but being not H at the same time; m and n are each 4-20). n EXAMPLE: 5-(8-Methylnonyl)-2-(4-octylphenyl)pyrimidine. n USE: Useful as a component of ferroelectric liquid crystal materials capable of realizing quick response. n PREPARATION: A reaction is made in the presence of sodium alcoholate between an amidine hydrochloride of formula II (R 1 is of formula V) and an alkylmalonic diester into a dihydroxy modification of formula III (R 2 is of formula VI), which is then put to halogen substitution using e.g. phosphorus oxychloride. Thence, the resulting dichlorinated modification of formula IV is dehalogenated in the presence of a base, thus giving the objective compound of the formula I. n COPYRIGHT: (C)1992,JPO&Japio |
