What are the physical properties of 4- [trans-4- (trans-4-butylcyclohexyl) -cyclohexyl] -1-ethoxy-2,3-difluorobenzene

4 - [trans-4- (trans-4-butylcyclohexyl) cyclohexyl] - 1-ethoxy-2,3-difluorobenzene, this compound has specific physical and chemical properties. Its appearance may be colorless, transparent to yellowish clear liquid, common in the field of display materials.

Let's talk about the melting point first. Due to the molecular structure containing large-volume cyclic and long-chain alkyl groups, the intermolecular forces are arranged in an orderly manner, and the melting point is within a certain range. The specific value depends on the precise synthesis and purification conditions.

In terms of boiling point, the molecular weight and intermolecular forces determine its boiling point. The cyclic structure and fluorine atoms enhance the intermolecular force, and the ethoxy and butyl chains increase the molecular weight, so that the boiling point of the compound is relatively high, ensuring its stable existence in a certain temperature range.

In terms of solubility, it is an organic compound. It follows the principle of "similar phase solubility" and is easily soluble in common organic solvents, such as toluene, chloroform, dichloromethane, etc., because these solvents and the compound molecules can form similar forces to promote dissolution; poor solubility in water, because it is non-polar or weakly polar, and the polarity is different from that of water molecules, making it difficult to interact and dissolve.

Dielectric anisotropy is key to its application in liquid crystal display. Molecules contain fluorine atoms and benzene ring structures. Fluorine atoms have high electronegativity, which causes the molecules to produce dipole moments. The dielectric anisotropy has a specific value. It can be arranged in order under the action of an electric field to realize the modulation of light in liquid crystal display.

Optical anisotropy is also important. The benzene ring and cyclohexyl structure form a conjugated system, which affects the molecular polarizability. Light in different directions acts differently with molecules to produce optical anisotropy. In liquid crystal display, the light propagation characteristics can be changed to achieve image display.

What is the synthesis method of 4- [trans-4- (trans-4-butylcyclohexyl) -cyclohexyl] -1-ethoxy-2,3-difluorobenzene

4 - [trans - 4 - (trans - 4 - butylcyclohexyl) - cyclohexyl] - 1 - ethoxy - 2,3 - difluorobenzene is an organic compound, and its synthesis method is complicated and requires multiple steps to achieve.

The first step is to prepare the key intermediate. 4 - butylcyclohexanone can be used as the starting material and reduced by a reduction reaction, for example, sodium borohydride is used as the reducing agent, and it is reduced to 4 - butylcyclohexanol in an alcohol solvent. This reaction condition is mild, and sodium borohydride selectively reduces carbonyl to hydroxyl, and the yield is quite high. Next, 4-butylcyclohexanol undergoes an intramolecular dehydration reaction in the presence of an acidic catalyst such as p-toluenesulfonic acid to form 4-butylcyclohexene. This reaction requires heating to promote the dehydration of the alcohol to form olefins, while p-toluenesulfonic acid can increase the reaction rate and yield.

Next step, another key intermediate is prepared. Using p-difluorobenzene as the starting material, under alkaline conditions, the reaction with sodium ethanol introduces an ethoxy group to generate 1-ethoxy-2,3-difluorobenzene. In this nucleophilic substitution reaction, the alkoxy negative ion of sodium ethanol attacks the halogenated position of p-difluorobenzene to form the target product.

Subsequently, the key intermediate undergoes a coupling reaction. The Heck reaction is carried out between 1-ethoxy-2,3-difluorobenzene and a previously prepared 4-butylcyclohexene derivative in the presence of a transition metal catalyst such as palladium. This reaction allows the two to be coupled to form a carbon-carbon bond, resulting in 4 - [trans-4- (trans-4 - butylcyclohexyl) - cyclohexyl] - 1 - ethoxy-2,3 - difluorobenzene. In the reaction, the palladium catalyst activates the carbon-halogen bond and the carbon-carbon double bond to promote the combination of the two. At the same time, a base needs to be added to neutralize the hydrogen halide generated by the reaction to improve the reaction efficiency.

After the reaction is completed, the product needs to be separated and purified. Column chromatography can be used, using silica gel as the stationary phase and a suitable eluent to elute, and the separation can be achieved according to the difference in the partition coefficients between the product and the impurities in the stationary phase and the mobile phase. After that, the product is further purified by recrystallization, a suitable solvent is selected, the product is dissolved at high temperature, and pure crystals are precipitated after cooling, so as to obtain high-purity 4 - [trans - 4 - (trans - 4 - butylcyclohexyl) - cyclohexyl] - 1 - ethoxy - 2,3 - difluorobenzene.
