In terms of physical properties, it usually appears as a white to light yellow solid powder with a certain melting point and boiling point. The melting point is about [X] ° C, and the boiling point is [X] ° C under specific pressure. Its solubility is manifested as good solubility in some organic solvents such as ethanol and acetone, but its solubility in water is relatively low.
II. Synthesis method
1. ** Classical organic synthesis path **: The traditional method of synthesizing 4-F4-fluorocinnamic Acid is mainly based on the improvement of Perkin reaction. With 4-tetrafluorobenzaldehyde and acetic anhydride as starting materials, under the action of basic catalysts such as sodium acetate, a condensation reaction occurs. During the reaction, the aldehyde group of 4-tetrafluorobenzaldehyde and the α-hydrogen of acetic anhydride undergo nucleophilic addition in an alkaline environment, and then undergo a series of reactions such as dehydration and rearrangement to generate 4-F4-fluorocinnamic Acid. The advantage of this method is that the raw materials are relatively easy to obtain, and the reaction conditions are easier to achieve in general organic synthesis laboratories. However, this method also has some limitations, such as the reaction yield is usually around [X]%, and the reaction time is long, generally [X] hours, and some by-products may be produced, such as the formation of impurities due to reactions such as the self-condensation of acetic anhydride.
2. ** Modern Catalytic Synthesis Strategies **: With the development of catalytic technology, some new synthesis methods have gradually emerged. For example, using transition metal catalysis, 4-halogenated tetrafluorobenzene and acrylic acid derivatives are used as raw materials, and under the action of transition metal catalysts such as palladium and copper and corresponding ligands, 4-F4-fluorocinnamic Acid is synthesized through carbon-carbon bond coupling reaction. This method has the advantages of mild reaction conditions and high yield. The yield can reach more than [X]%, and the reaction time can be shortened to about [X] hours. At the same time, by reasonably selecting ligands and reaction conditions, the selectivity of the reaction can be effectively controlled and the occurrence of side reactions can be reduced.
III. Chemical Reactivity
1. ** Double Bond Related Reaction **: The carbon-carbon double bond in the 4-F4-fluorocinnamic Acid molecule endows it with high reactivity. It can undergo typical addition reactions, such as addition with bromine water, to generate corresponding dibromogenic products. In the presence of light or peroxide, it can also undergo free radical addition reactions with hydrobromic acid and follow the anti-Markov rule. In addition, the double bond can also participate in the polymerization reaction. Under the action of the initiator, multiple 4-F4-fluorocinnamic Acid molecules can be connected to each other through the double bond to form a polymer with specific properties. This polymer has potential application value in the field of materials science.
2. ** Carboxyl-related reactions **: The carboxyl group is another important activity check point of 4-F4-fluorocinnamic Acid. It can be esterified with alcohols and reacted with methanol to form 4-F4-fluorocinnamic Acid methyl ester under the action of a catalyst such as concentrated sulfuric acid. Carboxyl groups can also neutralize with bases to generate corresponding carboxylic salts. These carboxylic salts may have unique properties and applications in some fields such as pharmaceutical preparations.
