What are the main uses of 1- (chloromethyl) -4- [ (1E) -2-nitrovinyl] benzene?
(1- (Cyanomethyl) -4- [ (1E) -2 -cyanovinyl] benzene, this substance is in the category of "Tiangong Kaiwu". Although this substance is not explicitly mentioned, it can be inferred from the ancient chemical technology insight, or from its raw material composition and reaction principle.
In ancient chemical industry, the selection of raw materials is quite critical. If viewed from this perspective, the raw materials of groups such as cyanomethyl and cyanovinyl, or from natural things, have been refined. In ancient times, people were familiar with extracting various basic substances from natural resources such as ores and plants. Such as metal ore refining metals, plant distillation to obtain fragrances, oils, etc. The cyanyl group of this substance is chemically converted from nitrogen-containing natural substances. Nitrogen is commonly found in animal and plant residues and soils, and can be converted into a cyanyl state through specific processes.
Besides the reaction process, the organic synthesis reaction requires suitable conditions. Although there was no modern advanced equipment in ancient times, there were many ingenious means. Heating, catalysis and other methods may be used. Heating can promote the activation of reactive molecules and increase the reaction rate. The method of catalysis, or the use of natural catalysts, such as certain metal ores, acid-base substances, etc., lowers the reaction threshold and makes the reaction more likely to occur.
From the use, it is speculated that substances containing such structures may emerge in the fields of dyes and medicine. The production of ancient dyes often seeks bright colors and durability. Such benzene-based structural substances can add color to fabrics due to their unique electron cloud distribution or good color properties. In medicine, natural organic compounds are often biologically active, and groups such as cyanide groups may interact with molecules in vivo to exert therapeutic effects. However, toxicity also needs to be carefully considered.)

What are the physical properties of 1- (chloromethyl) -4- [ (1E) -2-nitrovinyl] benzene
(1) Alkyl phenyl
This substance contains alkyl and phenyl structures. Alkyl groups have certain hydrophobicity, which makes the substance less soluble in polar solvents such as water; while phenyl groups, as conjugated systems, endow it with certain stability and special electronic effects. In terms of physical state, in view of the number of carbon atoms and the complexity of the structure, it may be liquid at room temperature, with certain fluidity, and due to the existence of intermolecular forces, it has a certain viscosity. Its density is slightly smaller than that of water and floats on the water surface.
(II) (1E) -2 -ethyl cyanoacrylate
1. ** State **: Most of them are liquid under normal conditions. Due to factors such as intermolecular forces and relative molecular mass, the liquid has moderate fluidity and is not extremely viscous or too thin.
2. ** Solubility **: The molecule of the substance contains polar groups such as cyanoyl and ester groups, but the overall structure has a certain non-polar part. Therefore, it has good solubility in organic solvents such as acetone and ethyl acetate, and can be mutually soluble with it; but it has poor solubility in water. Due to the strong polarity of water, it is incompatible with the partial non-polar structure of the substance.
3. ** Volatility **: There is a certain volatility, and the intermolecular force is not extremely strong. After a period of time in a room temperature environment, some molecules can overcome the intermolecular force and escape from the liquid surface into the gas phase.
4. ** Density **: The density is usually higher than that of water, and it will sink to the bottom when dropped into water.
5. ** Appearance **: In a pure state, it is generally colorless and transparent, similar to clear water, easy to observe and distinguish when using.

What are the chemical properties of 1- (chloromethyl) -4- [ (1E) -2-nitrovinyl] benzene
The chemical properties of (1- (cyanomethyl) -4- [ (1E) -2 -cyanovinyl] naphthalene are as follows:
In its molecular structure, the cyanomethyl group is connected to the naphthalene ring, and there is a specific (1E) -2 -cyanovinyl substituent at position 4 of the naphthalene ring. In terms of electronic effect, the cyanyl group is a strong electron-absorbing group. This structure changes the electron cloud distribution of the whole molecule and enhances the polarity of the molecule.
In terms of chemical reactivity, the presence of cyanyl groups makes this compound have unique reactivity. On the one hand, the cyanyl group can undergo hydrolysis, and under acidic or basic conditions, the cyanyl group is gradually converted into a carboxylic group or a carboxylate salt. For example, under alkaline conditions, the cyanyl group is first hydrolyzed to an amide and then hydrolyzed to a carboxylate. On the other hand, due to the electron-withdrawing action of the cyanyl group, the electron cloud density on the naphthalene ring decreases, so that the electrophilic substitution reaction activity on the naphthalene ring decreases, but under suitable conditions, the electrophilic substitution reaction can still occur, but the reaction check point will change compared with the ordinary naphthalene, and it is more inclined to be substituted at the position where the electron cloud density is relatively high
In addition, the carbon-carbon double bond in the (1- (cyanomethyl) -4- [ (1E) -2 -cyanovinyl] naphthalene molecule also has certain reactivity and can undergo addition reactions, such as addition with halogens, hydrogen halides and other electrophilic reagents to generate corresponding addition products. At the same time, in the presence of appropriate catalysts, polymerization may also occur to form polymers with specific structures.
In conclusion, this compound has potential application value in the field of organic synthesis due to its special molecular structure, cyano group and carbon-carbon double bond related chemical properties, and can be used as an intermediate for the synthesis of more complex organic compounds.)

What are the synthesis methods of 1- (chloromethyl) -4- [ (1E) -2-nitrovinyl] benzene?
To prepare 1- (cyanomethyl) -4- [ (1E) -2 -cyanovinyl] benzene, there are several methods for its synthesis.
First, benzene can be used as the starting material. First, a suitable reagent is used to introduce a halogen atom at a specific position in the benzene ring. The halogen atom has good activity and is convenient for subsequent reactions. Subsequently, under the action of a catalyst, a cyanomethyl-containing reagent undergoes a nucleophilic substitution reaction with a halogen-containing benzene, so that the cyanomethyl is connected to the benzene ring to obtain an intermediate product. Next, for the obtained intermediate product, a specific alkenylation reagent is selected, and under suitable reaction conditions, such as a specific temperature and the presence of a base, it is induced to react with cyanovinyl to construct the structure of the target product.
Second, benzene derivatives with a certain structure can also be used as starters. This derivative may already contain part of the target structure fragment, and it is converted into a functional group. For example, a functional group is first converted into an active group that is easy to react with cyanyl groups, and then reacted with cyanide-containing reagents to introduce a cyanyl group. Afterwards, through the alkenylation step, the (1E) -2 -cyanovinyl structure is constructed. This alkenylation reaction requires attention to the control of reaction conditions, such as reaction solvent, catalyst type and dosage, etc., in order to make the reaction proceed smoothly in the direction of the target product, and finally obtain 1- (cyanomethyl) -4- [ (1E) -2 -cyanovinyl] benzene.
Furthermore, the strategy of gradually constructing carbon-carbon bonds can also be considered. First, a suitable organometallic reagent reacts with a small molecule containing cyanide groups to form a carbon chain structure containing cyanide groups. At the same time, the benzene ring is suitably modified to have an activity check point connected to the above carbon chain structure. Then, the coupling reaction, such as the palladium-catalyzed coupling reaction, is used to connect the two, and then the complex structure of the target product is gradually constructed. During the whole process, each step of the reaction requires precise regulation of the reaction conditions to ensure the selectivity and yield of the reaction, and finally the desired 1- (cyanomethyl) -4- [ (1E) -2 -cyanovinyl] benzene is obtained.

What are the precautions for 1- (chloromethyl) -4- [ (1E) -2-nitrovinyl] benzene during storage and transportation?
During the storage and transportation of alkyl methyl, 1- (alkyl methyl) -4- [ (1E) -2 -furanyl vinyl] benzene, many matters need to be paid attention to.
First, because of its chemical properties, it must be stored in a cool, dry and well-ventilated place. Keep away from fire and heat sources to prevent chemical reactions caused by excessive temperature, resulting in material deterioration or potential safety hazards. The warehouse temperature should not exceed 30 ° C, and the relative humidity should be controlled below 80%.
Second, the substance needs to be stored separately from oxidants, acids, bases, etc., and must not be mixed. Because it may react violently with these substances, which may cause danger. Such as encounters with strong oxidizing agents, it may cause combustion or even explosion.
Third, during transportation, it is necessary to ensure that the container does not leak, collapse, fall, or be damaged. Transportation vehicles should be equipped with corresponding varieties and quantities of fire-fighting equipment and leakage emergency treatment equipment. If a leak occurs during transportation, personnel from the leakage contaminated area should be quickly evacuated to a safe area, and quarantined to strictly restrict access. Emergency personnel need to wear self-contained positive pressure breathing apparatus and anti-toxic clothing to cut off the source of leakage as much as possible. For small leaks, it can be absorbed by sand, vermiculite or other inert materials; for large leaks, it is necessary to build a dike or dig a pit for containment, cover it with foam to reduce steam disasters, and then transfer it to a tanker or a special collector with an explosion-proof pump, recycle it or transport it to a waste treatment site for disposal.
Fourth, it should be handled lightly to prevent damage to packaging and containers. Operators should be specially trained and strictly abide by the operating procedures. It is recommended that operators wear self-priming filter gas masks (half masks), chemical safety glasses, anti-poison penetration overalls, and rubber oil-resistant gloves.
