Synthesis and mesomorphic properties of some 3-substituted-4-cyanophenyl esters, 4′-cyano-3-substituted-4-biphenyl esters of 4-(trans-4-alkylcyclohexyl) benzoic, 4-alkyl-1,3-substituted biphenyl-4′-carboxylic, trans-4-alkylcyclohexanecarboxylic and 4-alkylbenzoic acids and electrooptic parameters of liquid-crystalline mixtures containing these compounds was written by Bezborodov, V. S.;Lapanik, V. I.;Adomenas, P.;Sirutkaitis, R.. And the article was included in Liquid Crystals in 1992.Computed Properties of C7H4BrNO This article mentions the following:
The reaction of trans-4-alkylcyclohexanecarboxylic acid chlorides, 4-alkylbenzoic, 4-(trans-4-alkylcyclohexyl)-benzoic, 4-alkyl-3-substituted biphenyl-4′-carboxylic acids with 4-hydroxy-3′-substituted benzonitriles and 4-hydroxy-3′-substituted-4′-cyanobiphenyls produced the corresponding esters. The mesomorphic properties of the esters and electrooptic and dynamic parameters of the mixtures containing these compound were studied. The liquid-crystalline mixtures containing 4-cyano-3-substituted-4′-biphenyl esters of 4-alkylbenzoic and trans-4-alkyl-cyclohexanecarboxylic acids have higher threshold voltages and saturation voltages in comparison with the analogous mixtures containing 4-cyano-3-substituted Ph esters of 4-(trans-4-alkylcyclohexyl)benzoic acids. In the experiment, the researchers used many compounds, for example, 2-Bromo-4-hydroxybenzonitrile (cas: 82380-17-4Computed Properties of C7H4BrNO).
2-Bromo-4-hydroxybenzonitrile (cas: 82380-17-4) belongs to nitriles. Nitrile function is a very important functional group because it can be manipulated to other functional groups such as carboxylic acid by hydrolysis or amine by reduction, respectively. Asymmetric bioreduction of nitriles is an attractive route to produce optically active nitriles as current metal-catalyzed hydrogenations tend to have low reactivity.Computed Properties of C7H4BrNO
