    Abstract: - ? : Preparation of explosion-proof trimethine salts of slight solubility in water which have the formula I (I) in which R is aryl or heteroaryl which is unsubstituted or mono or polysubstituted and X is the anion equivalent of a non-oxidizing acid radical which is inert towards the trimethine cation and can form trimethine salts of slight solubility in water, by formylation of compounds of the formula II R-CH2-COOH (II) in which R is as defined in formula I under the conditions of the Vilsmeier-Haack reaction, followed by hydrolysis of the formylation product in aqueous medium with the formation of water-soluble primary trimethine salts and reaction of the water-soluble primary trimethine salts in the aqueous reaction mixture with acids of the formula III (H)nX (III) in which X is as defined in formula I and n is a number from 1 to 3, or water-soluble salts thereof in at least stoichiometric amounts and separating off the resulting trimethine salts of slight solubility in water which have the formula I. Trimethine salts of the formula I are used as intermediates for the synthesis of heterocycles, preferably of pyrimidines and pyridines.

    Abstract: The novel liquid-crystalline mixtures (in the case of ferroelectric behavior they additionally contain an optically active compound as dope) are constructed from at least 2 mixture components of the general formula (I): (I) wherein n=6 to 14 and x=2 to 14. In addition, the mixtures may also contain cyclohexanecarboxylates of the general formula (II) (II) where R1=(C10-C16) or (C8-C14)alkoxy and R2=(C2-C9)alkyl, alkenyloxyphenylpyrimidine derivatives of the general formula (III) (III) where R3=(C7-C16)alkyl or (C6-C14)alkoxy and y=4-14, and/or alkoxyphenyl derivatives of alkylpyrimidine, of the general formula (IV) (IV) where m and p=6 to 14.

    Abstract: Phenylpyrimidinyl trans-cyclohexanecarboxylates of the formula … … form, in addition to a relatively broad nematic phase, a smectic C phase if R denotes an alkyl radical having 10 to 16 carbon atoms, in particular 11 to 16 carbon atoms, or an alkyloxy radical having 8 to 14 carbon atoms and R denotes an alkyl radical having 2 to 9 carbon atoms. Accordingly, they are suitable in particular as components of liquid-crystalline mixtures having a smectic C phase, since they induce a relatively broad nematic phase or widen a narrow nematic phase present and enlarge the temperature range of the smectic C phase towards low, but in particular towards high temperatures.

    Abstract: PCT No. PCT/EP87/00653 Sec. 371 Date May 5, 1989 Sec. 102(e) Date May 5, 1989 PCT Filed Nov. 2, 1987 PCT Pub. No. WO88/03525 PCT Pub. Date May 19, 1988.Arylcarboxylates of 2-hydroxypropionates are known, amongst other compounds, as dopes for converting tilted smectic liquid-crystal phases into ferroelectric liquid-crystal phases. The novel chiral aryloxypropionates of the general formula are two-fold chiral and in which the symbols have the following meaning: R1 denotes a straight-chain alkyl or alkoxy radical having 1 to 16 carbon atoms or a branched alkyl or alkoxy radical having 4 to 16 carbon atoms, it being possible for one or two non-adjacent CH2 groups to be replaced by a sulfur and/or oxygen atom; A denotes one, two or three aromatic or heteroaromatic rings which are linked to one another directly or via one or two COO groups; B denotes a chemical bond or one or two aromatic or heteroaromatic rings which are linked directly to one another; R2 (a) if B is a chemical bond, denotes an alkyl radical having 2 to 10 carbon atoms which contains an asymmetrical carbon atom which is substituted by CH3, halogen or a COOC2H5 group, or an alkyl radical having 3 to 10 carbon atoms which contains two adjacent, asymmetrical carbon atoms of which one is substituted by halogen and the other by a CH3 group, or which, together with an O, form an oxirane ring, or (b) if B denotes one or two aromatic or heteroaromatic rings which are bonded directly to one another, denotes alkoxy radicals having the same number of carbon atoms and the same structure of the alkyl group as under (a).
