What are the physical properties of 1-Ethenyl-4-Fluorobenzene?

1-Vinyl-4-fluorobenzene is one of the organic compounds. Its physical properties are quite critical and it is widely used in many fields of chemical industry.
First of all, its appearance is usually a colorless to light yellow transparent liquid, clear and pure, and pleasing to the eye. This liquid has a special smell. Although it is not pungent and intolerable, it also has a unique smell, which can be used as one of the identification characteristics.
In terms of boiling point, it is about a certain temperature range. This characteristic allows it to be distinguished from other substances by distillation and other means according to the difference in boiling point in the separation and purification process. Under a specific pressure, when it reaches the corresponding boiling point, the liquid will turn into a gas and rise, just like a phoenix nirvana, and the shape will change. The melting point of
is also an important physical property. Under certain low temperature conditions, the substance condenses from liquid to solid state, just like time solidification, giving it a different form. This property needs to be taken into account during storage and transportation, and a suitable temperature environment can ensure its morphological stability. The density of

What is the chemistry of 1-Ethenyl-4-Fluorobenzene?

1-Vinyl-4-fluorobenzene, with unique chemical properties, has the characteristics of both vinyl and fluorobenzene rings.
The presence of vinyl groups imparts unsaturation to this compound, allowing it to participate in addition reactions. Based on the generality of olefins, it can be added with many electrophilic reagents. In case of bromine water, the positive ion of bromine attacks the π bond of the vinyl group to form a dibromogen. This reaction is similar to the classical addition of olefins and bromine. The double bond breaks, and bromine atoms are added to the carbon atoms at both ends of the double bond, causing the color of bromine water to fade. The phenomenon is quite significant.
The fluorine atom is attached to the benzene ring. Due to the extremely high electronegativity of fluorine, it has a profound impact on the electron cloud density distribution of the benz It is an ortho-para-localization group. Although it reduces the electron cloud density of the benzene ring, it guides the electrophilic substitution reaction to occur mainly in the ortho-site and the para-site. In case of electrophilic reagents such as nitroyl positive ions, under appropriate conditions, nitrification can occur, and nitro groups are introduced into the ortho-site or para-site of the benzene ring.
This compound also has certain stability. The existence of the conjugate system of the benzene ring enhances the stability of the whole molecule. However, the activity of the vinyl group makes the molecule reactive. In the field of organic synthesis, the reactivity of vinyl can be used to introduce a variety of functional groups to build complex organic structures; and the stability of the benzene ring and the characteristics of fluorine atoms can be used to endow the product with special physical and chemical properties, such as affecting the polarity and solubility of molecules. It has potential application value in many fields such as medicinal chemistry and materials science.

What are 1-Ethenyl-4-Fluorobenzene synthesis methods?

The synthesis method of 1-vinyl-4-fluorobenzene has been known in ancient times, and its methods are various. Today, I will describe it in detail.
First, p-fluorobenzaldehyde can be started from p-fluorobenzaldehyde. First, p-fluorobenzaldehyde is reacted with phosphorylide reagent through Wittig. This reaction is also a classic method for constructing carbon-carbon double bonds in organic synthesis. The carbonyl group of aldehyde in p-fluorobenzaldehyde interacts with phosphorylide reagent, and through a series of complex electron transfer and chemical bond rearrangement, 1-vinyl-4-fluorobenzene can be obtained. This process requires attention to the precise control of reaction conditions, such as reaction temperature, solvent selection, etc. Too high or too low temperature can affect the rate and yield of the reaction. Usually, in a suitable organic solvent such as tetrahydrofuran, the reaction at low temperature to room temperature can achieve better results.
Second, use p-fluorobrobenzene as a raw material. First, it reacts with magnesium chips in anhydrous ethyl ether to form p-fluorophenyl magnesium bromide, which is a Grignard reagent. Then, this Grignard reagent reacts with halogenated acetylene derivatives such as acetynyl bromide or acetynyl iodine. The carbon-magnesium bond in Grignard's reagent has strong nucleophilicity, which can attack the carbon atom attached to the halogen atom of the halogenated acetylene derivative, and then form a carbon-carbon bond, and finally obtain 1-vinyl-4-fluorobenzene. In this synthesis path, the anhydrous and anaerobic conditions of the reaction system are very important, because Grignard's reagent is very active, and side reactions are prone to occur in contact with water or oxygen, resulting in a decrease in the yield of the target product.
Third, the coupling reaction catalyzed by transition metals is used. The reaction of p-fluoroiodobenzene with vinylboronic acid or vinylborate as raw materials is carried out in a suitable base and solvent system in the presence of transition metal catalysts such as palladium. Palladium catalysts can activate the chemical bonds of the reactants and promote the formation of carbon-carbon bonds. Common bases such as potassium carbonate and sodium carbonate, and solvents such as dioxane, N, N-dimethylformamide, etc. This method has relatively mild conditions, high selectivity, and is relatively friendly to the environment. It is widely used in modern organic synthesis.
Although the methods for synthesizing 1-vinyl-4-fluorobenzene are different, they all require fine operation and attention to the regulation of reaction conditions in order to obtain satisfactory results.

What is the price range of 1-Ethenyl-4-Fluorobenzene in the market?

At present, the price of 1-vinyl-4-fluorobenzene in the market is difficult to determine. The price of the cover varies due to many reasons, such as the state of supply and demand, the new technology, the price of raw materials and the competition in the market.
Looking at the past, the price of chemical industry often moves according to the times. If the demand for this product is wide and narrow, the price will rise; if the production is refined, the production increases and the cost decreases, the price may be depressed. And the price of raw materials is also the main reason. If the price of its source rises, the price of 1-vinyl-4-fluorobenzene may also rise.
The competition in the city cannot be ignored, and the merchants compete, or adjust the price for the purpose of attracting customers. In addition, the distance of the place and the difficulty of transportation also have an impact on the price. For distant goods, the transportation cost is imposed on them, and the price may be higher than that of the near producer.
Therefore, if you want to know the current market price of 1-vinyl-4-fluorobenzene, you should consult the chemical industry merchants, observe the trading platform, or visit the industry to get a more accurate price. The market is unstable, and the price is also variable, so you must observe it according to the situation.
