The physical and chemical properties of [ (Z) - (3,4-difluorobenzyl) (3-fluoro-4-oxo-cyclohexyl-2,5-diene-1-subunit) methyl] benzoic acid are as follows:
** 1. Physical properties **
1. ** Appearance **: Usually white to quasi-white crystalline powder. This is due to factors such as intermolecular forces and crystal structure, which cause it to exist in this form at room temperature and pressure. Many such organic compounds containing benzene rings and specific substituents are mostly crystalline powders.
2. ** Melting point **: Experimentally determined that its melting point is in a specific temperature range. This is mainly determined by the interaction forces between molecules, such as hydrogen bonds, van der Waals forces, etc. The rigidity of the benzene ring in the molecular structure and the properties of the substituents will affect the way the molecules are piled up, which in turn affects the melting point.
3. ** Solubility **: Slightly soluble in water. The reason is that although there are polar groups in the compound molecule, the overall benzene ring structure and longer carbon chain make it more hydrophobic. However, it is soluble in some organic solvents, such as dichloromethane, N, N-dimethylformamide, etc. This is because these organic solvents and compound molecules can form similar intermolecular forces, following the principle of "similar miscibility".
** Second, chemical properties **
1. ** Stability **: Under conventional temperature, humidity and light conditions, it has certain stability. However, in strong acid and alkali environments, reactions may occur. Because its molecular structure contains ester groups, hydrolysis reactions can occur under acid-base catalysis. At the same time, the substituents on the benzene ring may also undergo electrophilic substitution and other reactions under specific conditions.
2. ** Reactive activity **: The fluorine atoms on the benzene ring reduce the electron cloud density of the benzene ring. In the electrophilic substitution reaction, compared with benzene, the reactive activity is reduced, but such reactions can still occur. And the double bond on the side chain can undergo an addition reaction, and under suitable catalyst and reaction conditions, it can be added with hydrogen, halogen, etc.

To prepare this [ (Z) - (3,4-difluorobenzyl) (3-fluoro-4-oxo-cyclohexyl-2,5-diene-1-subunit) methyl] benzoic acid, according to the following ancient method:
First, with suitable starting materials, 3-fluoro-4-oxo-cyclohexyl-2,5-diene-1-subunit compound is obtained. The key intermediate of 3-fluoro-4-oxo-cyclohexyl-2,5-diene-1-subunit is obtained by a series of conversions of fluorine-containing aromatic compounds and alkenones with appropriate substituents under suitable catalysts and reaction conditions.
Simultaneously, 3,4-difluorobenzyl reagents were prepared. It can be started with 3,4-difluorotoluene, and through a halogenation reaction, a halogen (such as bromine or chlorine) is introduced into a halogen atom at the benzyl position under the action of light or an initiator to generate 3,4-difluorobenzyl halides. Then, it is formed with a metal reagent (such as magnesium to form a Grignard reagent, or reacted with a lithium reagent) to prepare an active 3,4-difluorobenzyl metal reagent.
Then the above two are combined in a suitable solvent (such as an ether or an aromatic hydrocarbon solvent) in the presence of a base to carry out a nucleophilic substitution reaction. The base can be selected from potassium carbonate, potassium tert-butyl alcohol, etc., which prompts the 3,4-difluorobenzyl metal reagent to nucleophilic attack on the specific position of the 3-fluoro-4-oxycyclohexyl-2,5-diene-1-subunit compound, forming a carbon-carbon bond, resulting in [ (Z) - (3,4-difluorobenzyl) (3-fluoro-4-oxycyclohexyl-2,5-diene-1-subunit) methyl] compounds.
