Nematic 4-cyanophenyl esters incorporating a lateral fluorine atom
نویسنده
چکیده
2014 We have investigated the dielectric, diamagnetic, and elastic properties of various 2-fluoroand 3fluoro-4-cyanophenyl esters. The esters are derivatives of benzoic, cyclohexane or bicyclooctane acids. For comparison we also measured the same properties of the corresponding non fluorinated esters. The change in the properties of the esters with either variation of the ring in the acid part of the ester with fixed position of the fluorine atom or with variation of the position of the fluorine atom with fixed ring structure is discussed. The physical properties of the esters have been found to be strongly dependent upon the presence and position of the fluorine atom. A very large value for the dielectric anisotropy of one of the esters has been determined. J. Physique 46 (1985) 1395-1404 Ao8T 1985; Classification Physics Abstracts 61. 30G

Dielectric Properties of Liquid Crystalline Isothiocyanato-tolane Derivatives with Fluorine Atom at Various Lateral Positions
Dielectric studies were performed for several isothiocyanato-tolane compounds having the F atom attached to the benzene rings at different lateral positions and the alkoxy or alkyl chain at the p-position. They form the nematic phase in broad temperature intervals. The static as well as dynamic properties of the compounds in the nematic and isotropic phases were studied. Tensor permittivity com...
متن کاملSynthesis, Characterization and Texture Observations of Calamitic Liquid Crystalline Compounds
Several divinylic mesogenic monomers were synthesized based on coupling the monomer 4-(4-pentenyloxy)benzoic acid with chlorohydroquinone, 2,5-dihydroxy- acetophenone, methylhydroquinone or 2-methoxyhydroquinone. This resulted in novel mesogens of phenylene esters with different lateral substituent groups. The effect of the lateral substituent group on the thermotropic phase behavior for these ...

The palladium-catalyzed reaction of 2,3,3-trifluoroallyl esters with several types of amines afforded trifluoromethylenamines, which were formed by the addition of a nitrogen nucleophile at the C-2 position and the intramolecular construction of the trifluoromethyl group via the fluorine atom shift from the C-2 to the C-3 position.
متن کاملAsymmetric allylic alkylation of Morita–Baylis–Hillman carbonates with α-fluoro-β-keto esters
In the presence of a commercially available Cinchona alkaloid as catalyst, the asymmetric allylic alkylation of Morita-Baylis-Hillman carbonates, with α-fluoro-β-keto esters as nucleophiles, have been successfully developed. A series of important fluorinated adducts, with chiral quaternary carbon centres containing a fluorine atom, was achieved in good yields (up to 93%), with good to excellent...
متن کاملHydrodefluorination of perfluoroalkyl groups using silylium-carborane catalysts.
Carbon-fluorine bonds are among the most unreactive functionalities in chemistry. Interest in their activation arises in part from the high global warming potentials of anthropogenic polyfluoroorganic compounds. Conversion to carbon-hydrogen bonds (hydrodefluorination) is the simplest modification of carbon-fluorine bonds, but efficient catalytic hydrodefluorination of perfluoroalkyl groups has...
