What is the synthesis method of 2 ', 4' -difluoro [1,1 '-biphenyl] -4-yl acetate

2% 27% 2C4% 27 - difluoro% 5B1% 2C1% 27 - biphenyl% 5D - 4 - yl acetate, that is, 2 ', 4' -difluorobiphenyl - 4 - yl acetate, the synthesis method is as follows:

First, 2,4 - difluorobenzene is used as the starting material, and a suitable alkyl group can be introduced through the Fu-gram alkylation reaction. This step requires careful selection of catalysts and reaction conditions to make the reaction proceed smoothly and ensure the selectivity of the product. After alkylation, halogen atoms are introduced at a suitable position through halogenation to prepare for the subsequent construction of the biphenyl structure. In the halogenation reaction, factors such as the amount of reaction reagents, reaction temperature and time need to be strictly controlled to obtain the ideal halogenated product.

Next, a palladium-catalyzed coupling reaction is used to connect halogenated aromatics with suitable phenylboronic acid or its derivatives to construct a biphenyl structure. This is a key step. The activity of the palladium catalyst, the selection of ligands, and the pH of the reaction system have a great impact on the efficiency and selectivity of the reaction. After the coupling reaction is completed, the biphenyl product is properly functionally converted to obtain a biphenyl intermediate with reactive groups that can be further reacted.

After this intermediate, an acetate group is introduced through an acetation reaction. The acetation reaction can be carried out with suitable acylating reagents, such as acetyl chloride or acetic anhydride, and carried out under appropriate alkali catalysis. During the reaction process, attention should be paid to controlling the reaction temperature and time to prevent side reactions from occurring, and to ensure that the acetate group is accurately introduced into the target position, so as to successfully synthesize 2 ', 4' -difluorobiphenyl-4 '-ylacetate. The whole synthesis process requires careful operation of each step of the reaction, and strict control of the reaction conditions to improve the yield and purity of the product.

What are the physical properties of 2 ', 4' -difluoro [1,1 '-biphenyl] -4-yl acetate

2% 27% 2C4% 27 - difluoro% 5B1% 2C1% 27 - biphenyl% 5D - 4 - yl acetate, this is the name of the organic compound, or the Chinese name is 2 ', 4' -difluoro- [1,1 '-biphenyl] - 4 - yl acetate. Its physical properties are as follows:

Looking at its properties, under room temperature and pressure, or in the state of white to light yellow crystalline powder, this kind of compounds containing benzene rings and ester groups have a regular structure and intermolecular forces cause them to exist in this form.

As for the melting point, it is deduced according to the characteristics of similar compounds, or in a specific range. Due to the presence of fluorine atoms in the molecule, the intermolecular force is enhanced, resulting in an increase in the melting point. Fluorine atoms have strong electronegativity, which can cause strong dipole-dipole interactions between molecules, so it is speculated that their melting point may be between [X] ° C and [X + Delta X] ° C.

When it comes to solubility, in organic solvents, because they contain ester groups, they have certain lipophilicity. Therefore, in halogenated hydrocarbon solvents such as chloroform and dichloromethane, they may have good solubility and can form a uniformly dispersed solution. In polar solvents such as water, it is difficult to form an effective interaction between ester groups and water molecules, so the solubility is poor, or slightly soluble or even almost insoluble. The density of

is relatively large due to the presence of benzene ring and fluorine atoms in the molecular structure, and the atomic arrangement is relatively close. It is speculated that its density is larger than that of water, and the specific value may be around [Y] g/cm ³.

In terms of volatility, due to the strong intermolecular force and the relatively large molecular weight, its volatility is weak, and it is difficult to volatilize into the gas phase at room temperature.
