What is the Chinese name of 1-chloro-4- (prop-1-en-2-yl) benzene?
1-Chloro-4- (1-propene-2-yl) benzene, this is the name of an organic compound. Looking at its name, it can be seen that its structure is based on the benzene ring, the 1-position of the benzene ring is connected to a chlorine atom, and the 4-position is connected to a (1-propene-2-group). (1-propene-2-group) is an unsaturated hydrocarbon group containing double bonds. The naming of this compound is based on the naming rules of organic chemistry, with the position and type of the substituent first, and then the main structure. The chlorine atom is used as a substituent to numerically represent its position in the benzene ring; (1-propylene-2-group) is also a substituent, so the name can accurately represent its chemical structure, so that organic chemistry researchers can know its structure by name, which is of great significance in research, synthesis, analysis, etc., and can help them accurately understand and manipulate related compounds.
What are the physical properties of 1-chloro-4- (prop-1-en-2-yl) benzene?
1 - chloro - 4 - (prop - 1 - en - 2 - yl) benzene, the Chinese name is often chloropropylene-based benzene. Its physical properties are as follows:
This substance is usually liquid under normal conditions. The outer color is close to the color to light, and the ground is clear and transparent, which seems to be difficult. Smell it, it has a special aroma, but the taste should not be long-lasting, because it has a certain irritation.
For boiling, it should be between 195 and 197 ° C. At this temperature, the 1-chloro-4- (prop-1-en-2-yl) benzene solution is low, usually around -40 ° C, so it is solid at normal temperature.
Its density is large. If the two are mixed, 1-chloro-4- (prop-1-en-2-yl) benzene will sink underwater. Moreover, the solubility of this substance in water is very small, and it is nearly insoluble. Because of the properties of benzene, chlorine atoms and allyl in its molecules, it can form an effective force on water molecules. However, it is soluble in many soluble substances, such as ethanol, ether, and acetone. This is because of the "similar miscibility", the soluble 1-chloro-4- (prop-1-en-2-yl) benzene has certain non-soluble properties.
In addition, 1-chloro-4- (prop-1-en-2-yl) benzene has a certain degree of stability. In an open environment, it can be heated to the air. Its vapor density is also greater than that of the air, so the vapor is easy to accumulate at a low temperature.

What are the chemical properties of 1-chloro-4- (prop-1-en-2-yl) benzene?
1-chloro-4- (prop-1-en-2-yl) benzene, or 1-chloro-4- (1-propylene-2-yl) benzene, has interesting chemical properties. This compound contains a benzene ring and an allyl chloride structure, and the chlorine atom activity of allyl chloride is higher.
First of all, the nucleophilic substitution reaction is one of its important properties. Due to the resonance stabilization of the positive ion of allyl carbon, the chlorine atom is easily replaced by nucleophilic reagents. In case of nucleophilic reagents such as sodium oxide, the nucleophilic ion of alcohol and oxygen attacks the carbon attached to the chlorine atom, and the chlorine leaves to form ether compounds. This reaction follows the mechanism of\ (S_ {N} 1\) or\ (S_ {N} 2\), depending on the reaction conditions.
Furthermore, it can undergo elimination reactions. Under the action of strong bases such as alcohol and potassium, chlorine atoms and hydrogen atoms on adjacent carbons are eliminated, forming double bonds, forming a conjugated diolefin structure, which has special stability due to conjugation effects.
In addition, the characteristics of the benzene ring cannot be ignored. It can undergo aromatic electrophilic substitution reactions, such as nitrification, sulfonation, etc. Because the allyl group is the power supply, the electron cloud density of the benzene ring is increased, and the electrophilic reagents are easy to attack the o and para. For example, in the mixed acid reaction with nitric acid and sulfuric acid, the nitro group mainly enters the ortho-position of the chlorine atom or the allyl para-position.
At the same time, the allyl moiety can undergo an addition reaction. Under suitable catalysts and conditions, it can be added with halogens, hydrogen halides, etc. If added with bromine, a dibromide is formed, the double bond is opened, and the bromine atom is added to the carbon at both ends of the double bond.
In short, 1-chloro-4- (1-propene-2-yl) benzene has a unique structure and has various chemical properties such as nucleophilic substitution, elimination, aromatic electrophilic substitution and allyl addition. It is widely used in the field of

What are the preparation methods of 1-chloro-4- (prop-1-en-2-yl) benzene?
1-Chloro-4- (propylene-1-ene-2-yl) benzene, also known as p-chlorophenyl vinyl, has the following common preparation methods:
First, p-chlorotoluene is used as the starting material, and chloromethylation is carried out with formaldehyde and hydrogen chloride to generate p-chlorobenzyl, which is then made into Grignard reagent with metal magnesium, and then reacts with acetylene, and finally is obtained by elimination reaction. This approach is more complicated, but the raw materials are relatively easy to obtain. The process is as follows: first, p-chlorotoluene is co-reacted with formaldehyde and hydrogen chloride under specific conditions. This step requires a specific catalyst and a suitable temperature to make the reaction proceed smoothly in the direction of generating p-chlorobenzyl chloride; then p-chlorobenzyl is prepared into Grignard reagent. The preparation of Grignard reagent requires an anhydrous environment, which requires quite high requirements; finally, it is reacted with acetylene and eliminated to obtain the target product.
Second, using p-chloroacetophenone as raw material, p-chlorobenzyl ethanol is first generated by reduction reaction, and then converted into p-chlorobenzyl chloride by halogenation reaction. The subsequent steps are the same as the above-mentioned method using p-chlorobenzyl p-Chloroacetophenone can be reduced to p-chlorophenyl ethanol by suitable reducing agents, such as sodium borohydride, etc. When halogenating, suitable halogenating agents, such as thionyl chloride, can be selected to generate p-chlorobenzyl, and then 1-chloro-4- (propylene-1-ene-2-yl) benzene is prepared according to the established route.
Third, using p-chlorostyrene as raw material, through addition reaction with chlorinated reagents, 1,2-dichloro-1- (4-chlorophenyl) propane is generated, and then the target product is prepared by elimination reaction. For the addition of vinyl chloride and chlorinated reagents, the conditions need to be properly controlled to ensure the addition location and product purity; for the subsequent elimination reaction, the appropriate base and reaction temperature need to be selected to promote the smooth elimination of the formation of 1-chloro-4- (propylene-1-ene-2-yl) benzene.
Different preparation methods have advantages and disadvantages. In actual production, many factors such as raw material cost, reaction conditions, product purity and yield need to be comprehensively considered to select the most suitable method.
