What are the synthesis methods of 4- [4-trans- (3,4-difluorophenyl) cyclohexyl] cyclohexanone

To prepare 4 - [4 - trans - (3,4 - dihydrophenyl) cyclohexyl] cyclohexanone, there are various methods. Ancient compounds often rely on all kinds of ingenuity and techniques.

First, suitable ketenes can be started. First, take the ketenes, make them with a specific aryl halide, and react under the action of a suitable catalyst, such as a palladium-based catalyst. This reaction requires the selection of an appropriate solvent, such as dimethylformamide, and temperature control and time control to make the reaction smooth, to obtain an intermediate containing aryl groups. Then, the intermediate is hydrogenated, and a metal catalyst, such as platinum, palladium, etc., is used to hydrogenate the ethylene bond in a hydrogen atmosphere to obtain a product with a desired carbon frame. After the oxidation step, a suitable oxidizing agent, such as Jones reagent, etc., oxidizes the specific group in the product to a ketone group, and finally obtains the target 4- [4-trans - (3,4-dihydrophenyl) cyclohexyl] cyclohexanone.

Second, it can also start with cyclohexanone derivatives. Modify cyclohexanone, introduce suitable substituents, and construct a reactive activity check point. After multi-step reactions, such as alkylation, cyclization, etc. First, cyclohexanone derivatives are treated with strong bases to generate carbon anions, and then react with halogenated hydrocarbons containing aryl groups to perform alkylation and introduce aryl fragments. Then, the desired double-cyclic structure is constructed by intramolecular cyclization reaction. The degree of unsaturation of the aromatic ring is adjusted by hydrogenation, and finally the target ketone structure is obtained by oxidation.

Third, there is a strategy that can be started by aryl cyclohexanol. First, the aryl cyclohexanol is oxidized and converted to aryl cyclohexanone. After that, the carbon chain is extended and the second cyclohexyl structure is constructed by reacting with a suitable electrophilic reagent using enol anion chemistry. By controlling the reaction conditions, the generated product has the desired trans configuration. The synthesis of 4 - [4 - trans - (3,4 - dihydrophenyl) cyclohexyl] cyclohexanone is achieved by hydrogenation, oxidation and other steps. Each method requires careful control of the reaction conditions and weighing the advantages and disadvantages of each step to achieve efficient and pure synthesis.

What are the physical properties of 4- [4-trans- (3,4-difluorophenyl) cyclohexyl] cyclohexanone

4 - [4 - trans - (3,4 - dihydrophenyl) cyclohexyl] cyclohexenone, this physical property is quite complex, let me tell you in detail.

Looking at its molecular structure, it is composed of unique carbon rings and substituents. Its physical form may be in a solid state at room temperature, due to relatively strong intermolecular forces, resulting in a certain degree of stability.

When it comes to melting point, the melting point is high because of the interaction of multiple carbon rings in its structure, which makes the molecules closely arranged. The interaction between Van der Waals forces and hydrogen bonds between molecules requires more energy to overcome the lattice energy before it can change from solid to liquid. The boiling point of

is also not low, the large molecular mass formed by multiple carbon rings, and the strong interaction between molecules caused by the complex structure increase the energy required for gasification. To make it boil, a large amount of heat needs to be supplied to break the binding of intermolecular forces.

In terms of solubility, due to the large proportion of its non-polar carbon ring structure, it has good solubility in non-polar organic solvents such as benzene and toluene. Non-polar solvents and the non-polar part of the compound can interact through van der Waals forces to promote solubility. However, in polar solvents such as water, the solubility is poor. Because it is difficult to form an effective interaction with water molecules, and the polarity difference is large, it follows the principle of "similar miscibility", so it is not easily soluble in water.

The density is slightly higher than that of water, which is due to the relatively dense carbon atoms in the molecule and the concentrated atomic mass, resulting in a large mass per unit volume.

In addition, the compound may have certain optical activity. If there is a chiral center in the structure, or it exhibits optical rotation characteristics under polarized light. This property is derived from the asymmetry of its molecular structure and can be used in research and application in optics-related fields.

In summary, the physical properties of 4 - [4 - trans - (3,4 - dihydrophenyl) cyclohexyl] cyclohexenone are determined by its unique molecular structure, which is of great significance in the research and application of organic chemistry and related fields.

What are the storage conditions for 4- [4-trans- (3,4-difluorophenyl) cyclohexyl] cyclohexanone?

4 - [4 - trans - (3,4 - dihydrophenyl) cyclohexyl] cyclohexanone is an organic compound, and its storage conditions need to be carefully.

This compound has certain chemical activity and is easily deteriorated by external factors, which in turn affects its chemical properties and use efficiency. Therefore, when storing, the temperature and humidity of the first environment should be stored in a cool place, and the temperature should be maintained at 2-8 ° C. Such a low temperature environment can effectively slow down the rate of molecular movement, inhibit the occurrence of chemical reactions, and reduce the risk of compound deterioration. And the humidity should also be strictly controlled, and it should be kept in a relatively dry state. Generally, the humidity should be controlled at 40% - 60%. Due to high humidity, it is easy to cause the compound to absorb moisture, which may cause adverse reactions such as hydrolysis and destroy its chemical structure.

Light is also a key factor. This compound is sensitive to light, and photochemical reactions may occur under light, causing its structure to change. Therefore, when storing, it should be placed in an opaque container, such as a brown glass bottle, to block light exposure and ensure its stability.

In addition, the storage place should be well ventilated. Good ventilation can avoid compound volatilization and accumulation, reduce safety hazards, and prevent unnecessary reactions with other substances in the air. At the same time, it needs to be stored separately from oxidants, acids, bases and other substances. Due to its chemical properties, contact with these substances may cause severe chemical reactions, endangering storage safety.

During storage, the state of the compound should also be checked regularly, such as to observe whether there are any abnormal phenomena such as discoloration and precipitation, to ensure that its quality is stable and ready for subsequent use.
