Abstract:
Optionally-substituted 2-fluoro-4'-phenoxydifluoromethyl-biphenyl compoundes are new. Compounds of formula (I) are new. R 1> : H, F, Cl, Br, optionally halogenated 1-15C alkyl (optionally with in-chain -Ctriple boundC-, -CH=CH-, -COO-, -OCO-, -CO- or -O-); A 1> : trans-1,4-cyclohexylene or cyclohexenylene (both optionally substituted with F and/or having non-adjacent CH 2 group(s) replaced by O and/or S), or 1,4-phenylene (optionally with 1 or 2 CH groups replaced by N and/or with one or more H replaced by Br, Cl, F, CN, methyl, methoxy, fluorinated methyl or fluorinated methoxy); Z 1> : single bond, -CH 2O-, -COO-, -CF 2O-, -CH 2CH 2CF 2O-, -CF 2CF 2-, -CH 2CF 2-, -CH 2CH 2-, -(CH 2) 4-, -CH=CH-, -CH=CF-, -CF=CF- or -Ctriple boundC-; L 1>, L 2> : H or F; X 1> : F, Cl, CN, NCS, SF 5, or 1-7C halogenated alkyl, alkoxy, alkenyl or alkenyloxy; a : 0, 1 or 2. Independent claims are also included for (1) a method (M1) for the production of (I) by reacting boronic acids or esters of formula (IIA) or (IIB) with compounds of formula (III) in presence of transition metal catalysts (2) a method (M2) for the production of (I) by reacting compounds of formula (IV) with boronic acids or esters of formula (V) in presence of transition metal catalysts (3) liquid crystalline (LC) media with at least two mesogenic components, containing at least one compound (I) (4) electro-optical LC displays containing such media. R 3>, R 4> : 1-12C alkyl, or R 3>+R 4> = alkylene or phenylene (all optionally substituted); Hal : -O(SO 2)CF 3, Cl, Br or I. [Image] [Image] [Image] [Image].
