What are the chemical properties of 3-Chloro-4- (3-fluoro-benzyloxy) phenylamine?

3-Chloro-4- (3-fluorobenzoxy) aniline, this is an organic compound. Its chemical properties are unique and of great research value.

Looking at its structure, it contains groups such as chlorine atoms, fluorobenzoxy groups and amino groups. Chlorine atoms have certain electronegativity, which can affect molecular polarity and reactivity. Because their electronegativity is greater than that of carbon, the electron cloud will tilt towards itself, making the connected carbon atoms partially positively charged, which is easy to initiate nucleophilic substitution reactions. Under appropriate conditions, chlorine atoms can be replaced by other nucleophilic reagents to form new carbon-hetero atomic bonds.

In 3-fluorobenzoxy groups, fluorine atoms have extremely strong electronegativity, which has a significant impact on the distribution of part of the electron cloud of benzoxy groups Its electron-withdrawing effect makes the benzoxy group more stable, and also affects the electron cloud density of the benzene ring connected to it. This not only changes the activity and selectivity of the electrophilic substitution reaction of the benzene ring, but also plays a role in the overall physical and chemical properties of the molecule, such as boiling point, melting point, etc. The

amino group is a strong electron-giving group, which can significantly increase the electron cloud density of the benzene ring, making the benzene ring more prone to electrophilic substitution reaction. There are lone pairs of electrons on the amino nitrogen atom, which can participate in a variety of chemical reactions, such as reacting with acids to form salts, reacting with acyl halides, acid anhydrides, etc. to form amides. And under certain conditions, amino groups can also undergo diazotization reactions, etc., providing rich pathways for organic synthesis Due to the interaction of these groups, 3-chloro-4- (3-fluorobenzyloxy) aniline exhibits diverse chemical properties and can be used as a key intermediate in the field of organic synthesis for the preparation of various bioactive or special functional organic compounds. It may have potential applications in the pharmaceutical, pesticide and other industries.

What is the synthesis method of 3-Chloro-4- (3-fluoro-benzyloxy) phenylamine?

To prepare 3-chloro-4- (3-fluorobenzoxy) aniline, the synthesis method is obtained by multi-step reaction.

The first step is to use 3-chloro-4-hydroxyaniline as the starting material, and the hydroxyl group in this compound is reactive. Take it and react with 3-fluorobenzyl halides, such as 3-fluorobenzyl chloride or 3-fluorobenzyl bromide, in an alkaline environment. Potassium carbonate, sodium carbonate, etc. are commonly used in basic reagents, and they are heated and stirred in suitable solvents, such as N, N-dimethylformamide (DMF), acetonitrile, etc. The base can capture the hydrogen of the hydroxyl group of 3-chloro-4-hydroxyaniline to form a phenoxy negative ion. This negative ion has strong nucleophilicity and attacks the benzyl carbon of 3-fluorobenzyl halide. The halogen ion leaves, thereby generating a 3-chloro-4- (3-fluorobenzoxy) aniline precursor. This step is a nucleophilic substitution reaction.

However, the resulting product or impurities need to be separated and purified. The column chromatography method can be used to use silica gel as the stationary phase, and the suitable mixed solvent is the mobile phase. For example, petroleum ether and ethyl acetate are mixed in a certain proportion. According to the difference in the partition coefficients of different compounds in the stationary phase and the mobile phase, separation is achieved to obtain a pure 3-chloro-4- (3-fluorobenzyl halophenoxy) aniline intermediate.

Last step, if the halogen atom in the intermediate is not an amino group, it needs to be converted. If the intermediate is 3-chloro-4- (3-fluorobenzoxy) halobenzene, the nucleophilic substitution reaction can be used to replace the halogen atom with an ammonia or amine reagent under suitable conditions. For example, in an autoclave, liquid ammonia is used as the ammonia source, and an appropriate amount of catalyst, such as copper salts, is added to heat the reaction, the halogen atoms leave, and the ammonia molecules attack the benzene ring carbon to form the target product 3-chloro-4- (3-fluorobenzoxy) aniline. The final product also needs to be purified, which can be recrystallized, and a suitable solvent, such as ethanol and water, is selected. After dissolving, cooling and crystallizing, filtering and drying, high-purity 3-chloro-4- (3-fluorobenzoxy) aniline is obtained.
