What are the physical properties of 2- (bromomethyl) -1-chloro-4-iodobenzene

2-%28bromomethyl%29-1-chloro-4-iodobenzene, the Chinese name is 2- (bromomethyl) -1 -chloro-4 -iodobenzene. This compound is a compound with special physical properties.
Its external properties are often solid, or slightly poor due to degree and environmental factors. In terms of melting, some compounds are often affected by different molecular forces and factors. This compound contains bromine, chlorine, iodine and other atoms. The molecular force is low, and the melting time is not low. However, the cutting value needs to be refined.
In terms of solubility, according to the principle of similarity dissolution, the solubility of the compounds is excellent in non-soluble or weak solubility such as toluene and dichloromethane; the solubility of the molecules is such as water, and the solubility is poor because of its molecular integrity.
The density is also important for physical properties. The atomic weight of the atoms in the molecule is high, so that its density is more likely to be higher than that of normal solubility, or close to or exceed the density of water, and it has the property of sinking in the aqueous phase.
In terms of solubility, the general solubility of the compounds is small. Due to the molecular force, the molecular fusion density is low, and the vapor density is not high.
In addition, its qualitative properties are specific. Contains multiple atoms, chemical activity, in the presence of light, oxygen or catalysis, or inducing reaction, such as the substitution of oxygen atoms, etc., so specific materials are required, protected from light, high temperature, anti-decomposition, and anti-reaction.

What are the chemical properties of 2- (bromomethyl) -1-chloro-4-iodobenzene

2-%28bromomethyl%29-1-chloro-4-iodobenzene, that is, 2 - (bromomethyl) -1 -chloro-4 -iodobenzene, this is an organohalogenated aromatic hydrocarbon compound. Its chemical properties are unique and related to many chemical reaction mechanisms, which will be described in detail below.
In the molecule of this compound, bromomethyl, chlorine atoms and iodine atoms are all active functional groups. Among them, the carbon-bromide bond of bromomethyl is highly electronegative due to the large electronegativity of the bromide atom, resulting in a polar carbon-bromide bond, and carbon is partially positively charged, so it is vulnerable to attack by nucleophiles and nucleophilic substitution For example, when encountering hydroxyl negative ions (OH), the hydroxyl negative ions will attack the carbon atoms of bromomethyl with their lone pairs of electrons, and the bromide ions leave to form 2- (hydroxymethyl) -1 -chloro-4 -iodobenzene.
Furthermore, although chlorine atoms and iodine atoms are slightly less active than bromomethyl atoms, they can also participate in the reaction under certain conditions. At high temperatures or in the presence of catalysts, chlorine atoms or iodine atoms can be replaced by other nucleophiles. Due to the large radius of iodine atoms and the relatively small C-I bond energy, sometimes iodine atoms are more easily replaced. For example, under the catalysis of some metals, iodine atoms can be replaced by alkyl, aryl and other substituents to achieve functionalization on the benzene ring, thereby expanding the structural diversity of the compound.
In addition, the benzene ring in this compound can undergo electrophilic substitution due to its conjugated π electron system. However, because the halogen atoms such as chlorine and iodine are ortho-para-sites and have electron-absorbing induction effects, the electron cloud density of the benzene ring will be reduced, and the reactivity is slightly lower than that of benzene. When the electrophilic reagent attacks, it mainly occurs in the ortho and para-sites of the halogen atom. For example, the mixed acid reaction with nitric acid and sulfuric acid can generate nitro-substituted products.
Due to the presence of multiple halogen atoms in the molecule, under the action of metal reagents, coupling reactions between halogen atoms may occur to build carbon-carbon bonds and form more complex organic structures.
2- (bromomethyl) -1-chloro-4-iodobenzene has important application value in the field of organic synthesis due to its unique chemical properties.

What are the synthesis methods of 2- (bromomethyl) -1-chloro-4-iodobenzene

To prepare 2 - (bromomethyl) -1 - chloro - 4 - iodobenzene, there are two common methods.
First, start with p-chloroiodobenzene. First, it is heated with paraformaldehyde, concentrated hydrochloric acid and zinc chloride, and the reaction is chloromethylated to obtain 1 - chloro - 4 - iodo- 2 - (chloromethyl) benzene. In this reaction, under the action of concentrated hydrochloric acid and zinc chloride, paraformaldehyde releases active formaldehyde species, attacks the benzene ring ortho-position of p-chloroiodobenzene, and introduces chloromethyl. Then, sodium bromide and 1 - chloro - 4 - iodine - 2 - (chloromethyl) benzene in a suitable solvent, such as N, N - dimethylformamide, heating reaction, bromine ions through nucleophilic substitution, instead of chlorine atoms, then 2 - (bromomethyl) - 1 - chloro - 4 - iodobenzene.
Second, start with p-chlorobenzyl alcohol. First, iodizing reagents, such as sodium iodide and triphenylphosphine and diethyl azodicarboxylate, so that the hydroxyl group is replaced by iodine, to obtain p-chloroiodobenzyl alcohol. This reaction goes through a multi-step mechanism. Triphenylphosphine and diethyl azodicarboxylate synergistically activate the hydroxyl group, so that the iodine ion of sodium iodide is easy to attack and complete the substitution. After that, p-chloroiodobenzyl alcohol reacts with hydrobromic acid and an appropriate catalyst, such as sulfuric acid, and the hydroxyl group is replaced by bromine, resulting in the final product 2- (bromomethyl) -1 -chloro-4 -iodobenzene. In this process, sulfuric acid catalyzes the substitution reaction of hydrobromic acid and alcohol, which prompts the reaction to proceed to

2- (bromomethyl) -1-chloro-4-iodobenzene what to pay attention to when storing and transporting

2-%28bromomethyl%29-1-chloro-4-iodobenzene is 2- (bromomethyl) -1 -chloro-4 -iodobenzene. This is an organic compound. When storing and transporting, many aspects need to be paid attention to.
Let's talk about storage first. Because it has certain chemical activity, it must be placed in a cool, dry and well-ventilated place. A dark place away from light can prevent chemical reactions caused by light. Moisture can easily cause material deterioration. Good ventilation can reduce the risk of dangerous gas accumulation. The temperature should be kept stable, with large temperature fluctuations or changes in the physical and chemical properties of the compound. It should be stored separately from oxidants and strong bases. Due to contact with oxidants or violent reactions, uncontrollable reactions with strong bases may also occur. Storage containers should be corrosion-resistant and well-sealed. Glass or specific plastic containers are more suitable to ensure that they are not in contact with air, moisture, etc.
Let's talk about transportation. Before transportation, make sure that the packaging is tight, packed according to the relevant standards of hazardous chemicals, with warning labels indicating the characteristics and hazards of the substance. The means of transportation should be clean, dry and free of other substances that may react with it. Avoid bumps and vibrations during transportation to prevent package damage. Transportation regulations need to be strictly followed. Transportation personnel should be professionally trained and familiar with the characteristics of the compound and emergency treatment methods. If the packaging is damaged during transportation, emergency measures should be taken immediately, evacuate personnel, seal the scene, and professional personnel should clean up and dispose of it.
