Two Liquid Crystal Phases with Nematic Morphology in Laterally Substituted Phenylenediamine Derivatives

Abstract: Bis-(4′-n-alkoxybenzal)-2-chloro-1, 4-phenylenediamines and bis- (4′-n-alkoxybenzal)-2-methyl-1, 4-phenylenediamines with different alkoxy groups have been synthesized. Similar compounds with fluoro, bromo and chloro groups replacing the alkoxy groups have also been prepared. All the compounds show a nematic liquid phase. An additional lower temperature liquid crystalline phase is observed with chloro-substituted compounds for n-alkoxy chain lengths of C8 and longer and with the methyl substituted compounds for chain lengths of C10 and longer. This lower temperature phase can show a threaded texture very similar to the nematic phase. Furthermore, both phases can be uniformly oriented by surface action and can assume a twisted structure. We suppose that the lower temperature phase has a layered structure in which the molecules are inclined to the layers, and that it corresponds to a smectic liquid crystal classified by Sackmann and Demus as smectic C.

Phenoxy carboxylic acid derivative

Abstract: Novel anti-atherosclerosis agents having the formula, WHEREIN TYPICAL EXAMPLES OF R1 and R2 are hydrogen, C1-C8 alkyl, phenyl, benzyl and phenethyl, or R1 and R2 may form cycloalkylidene together with a carbon atom bonded therewith; R3 and R4 each is hydrogen or C1-C4 alkyl; Y is hydroxyl, C1-C4 alkoxy, phenoxy or an amine residue; A is hydrogen or a group of the formula, WHEREIN R3, R4 and Y have the same meanings as defined above; and D and E each is hydrogen or halogen. These compounds are produced, for example, by reacting a bisphenolic compound of the formula, in the presence of an alkali. Alternatively, they are produced by reacting the bisphenolic compound with Alpha -halogeno- or Alpha -hydroxycarboxylic acid derivative of the formula, WHEREIN R1, R2, R3, R4, D, E and Y have the same meanings as defined above; and X is halogen or hydroxyl.

Nonionic detergent degradation: III. Initial mechanism of the degradation

Abstract: In Parts I and II of this series (1,2), degradation and foaming experiments on a number of commercially available alcohol polyethoxylates and alkyl phenol polyethoxylates are described. This paper describes an extension of the thin layer chromatographic work on which the experiments described earlier were based, supplemented by a variety of other chemical and physical tests to provide some insight into the initial mechanism of degradation of these materials before they disappear by the established oxidation and hydrolytic routes. In the case of the readily degradable alcohol ethoxylates, two distinct mechanisms are shown to proceed simultaneously: a fission of the molecule into hydrophobic and hydrophilic entities, and a rapid oxidation of the hydrophobic group. No fission occurs in the case of the alkyl phenol ethoxylates, the more usual route of degradation being slow oxidation and hydrolysis of the alkyl groups, the aromatic ring and the ethoxy chain simultaneously; occasionally, and at higher pH, the hydrolysis of the ethoxy chain proceeds at a considerably increased rate.

Die Wohl‐Ziegler‐Bromierung von Tiglin‐ und Angelika‐säureestern

Abstract: The Wohl-Ziegler bromination (with N-bromo-succinimide = NBS) of methyl tiglate (1b) gave a 2:1 mixture of methyl γ-bromotiglate (3b) and methyl β′-bromotiglate (5b). This ratio of γ- to β′-bromination was unaffected by changes of solvent, catalyst or size of the ester alkoxy group. The same products were obtained from the NBS treatment of methyl angelate (2b). This NBS-bromination appears to be thermodynamically controlled, since both angelic and tiglic acid as well as their methyl esters were brought into equilibrium (1 ⇆ 2 = > 9:1) with catalytic amounts of NBS.

Hemi-alkoxides from reactions of trimethylaluminium with aldehydes or ketones

Abstract: One mole of an aldehyde or ketone reacts stoicheiometrically with one mole of trimethylaluminium dimer at ambient temperature in hydrocarbon solvents to form a "hemi-alkoxide" in which an alkoxy group and a methyl group bridge two aluminium atoms. Benzaldehyde, acetone, acetophenone, benzophenone, and cyclohexanone give p-alkoxy-p-methyl-tetramethyldialuminiums (Me2A1.OR.Me.AlMe2; R = CHPhMe, But, CphMea2 CPh2Me, and 1-methylcyclohexyl, respectively). Such compounds can also be prepared in low yields starting from alcohols, rather than aldehydes or ketones. The analogous compound, NezAl.N=CPhMe.Me.AlMez, is formed by reaction of benzonitrile with one mole of trimethylaluminium dimer in the absence of solvent at 100o. Exchange of methyl groups between bridge and terminal sites in these new compounds has been studied by proton magnetic resonance spectroscopy.

Mass spectrometry in structural and stereochemical problems–CLXXXIX: Electron‐impact induced fragmentations and rearrangements of alkoxycyclohexanol trimethylsilyl ethers and alkoxycyclohexyl trimethylsilanes

Abstract: In view of the current interest in the electron-impact induced rearrangements of both trimethylsilyl derivatives and bifunctionalized cyclohexanes, the mass spectral properties of several alkoxycyclohexanol trimethylsilyl ethers and alkoxycyclohexyl trimethylsilanes have been investigated. Using deuterium labeling, the basic fragmentation modes incurred upon electron-impact of ethanol trimethylsilyl ether were elucidated. The major peaks in the spectrum of this simple ether occur also in those of the title compounds, the latter fragments having been formed by interaction of the two functional groups. Thus the initial rearrangement ion of mass 103 (e) from electron bombardment of 4-ethoxycyclohexanol trimethylsilyl ether and 2-ethoxycyclohexyl trimethylsilane corresponds to the [M CH3] ion from ethanol trimethylsilyl ether. Its further fragmentation has been studied using high resolution and metastable ion measurements, and the scope of the interaction between the alkoxy and trimethylsilyl groups, when silicon is attached both to oxygen and to carbon, has been determined. In addition, the origin of every ‘characteristic’ fragment ion has been elucidated on the basis of each corresponding peak in the spectra of several derivatives labeled specifically with deuterium. Peaks derived from initial ionization of both functionalities in each compound have been observed, although the majority of ions in the spectra of both series seem to be directed by fragmentations associated with the trimethylsilyl ether moiety.
