First take an appropriate amount of biphenyl as the initial raw material, in a specific reaction vessel, use iron filings as the catalyst, slowly add liquid bromine dropwise, and control the temperature to about 50 to 60 degrees Celsius. This is an electrophilic substitution reaction. The bromine atom is acted by the catalyst to attack the biphenyl ring and generate 4-bromobiphenyl. The reaction mechanism is that the iron filings react with bromine to form iron bromide, which polarizes the bromine molecule, making it easier to attack the benzene ring electrophilically.
After 4-bromobiphenyl is formed, an appropriate amount of iodine is added to it as a substrate, and a copper salt is used as a catalyst to heat it to 80 to 90 degrees Celsius in an organic solvent. Under the catalysis of copper salt, iodine atoms replace 4-bromobiphenyl para-hydrogen atoms to obtain 4-Iodo-4 '-Bromobiphenyl. The catalytic mechanism of this step is that the copper salt interacts with iodine to enhance the activity of iodine and promote the substitution reaction. In this way, after a two-step reaction, the target product can be obtained.

What are the synthesis methods of 4-iodo-4 '-bromobiphenyl?

To make 4-iodo-4 '-bromobiphenyl, there are three methods.
First, start with biphenyl, and go through the sequence of bromination and iodization. First, make biphenyl and bromine under the catalysis of iron or iron salt, in the heated state, electrophilic substitution to obtain 4-bromobiphenyl. In this step, bromine electrophilic attacks the biphenyl ring. Due to the uneven electron cloud density of the benzene ring, the 4-position is more active, and the bromine atom is easy to occupy. Later, 4-bromobiphenyl and iodine reagents, such as iodosuccinimide (NIS), in an appropriate solvent, such as dichloromethane, add an initiator, light or heat, so that iodization occurs, and the target is obtained.
Second, 4-bromo-4 '-aminobiphenyl is prepared by diazotization and iodine substitution. First, 4-bromo-4' -aminobiphenyl is diazotized with sodium nitrite in hydrochloric acid medium at low temperature to obtain diazonium salts. This diazonium salt is extremely active, and then interacts with potassium iodide or sodium iodide solution. The diazoyl group is replaced by iodine atoms to form 4-iodo-4 '-bromobiphenyl.
Third, 4-bromophenylboronic acid is coupled with 4-iodobromobenzene through Suzuki. In the presence of a base, such as potassium carbonate, a palladium complex as a catalyst, such as tetra (triphenylphosphine) palladium (0), is heated in a suitable solvent, such as a mixed solvent of dioxane and water. In this reaction, the boron group of 4-bromophenylboronic acid and the halogen atom of 4-iodobromobenzene are coupled to form a carbon-carbon bond under palladium catalysis to obtain 4-iodo-4 '-bromobiphenyl. Each method has its own advantages and disadvantages, and it needs to be selected according to the actual situation, such as the availability of raw materials, cost, yield, etc.

What are the physical properties of 4-iodo-4 '-bromobiphenyl?

4-Iodo-4 '-bromobiphenyl is an organic compound. Its physical properties are particularly important and are of key significance in chemical research and industrial applications.
First of all, its appearance is often in the state of white to light yellow crystalline powder, which is convenient for preliminary identification. Looking at its color and morphology can help chemists preliminarily judge its purity and state in experiments or production processes.
Second-round melting point, 4-iodo-4' -bromobiphenyl has a high melting point and usually melts within a specific temperature range. The high melting point is due to the intermolecular force, and its molecular structure makes the intermolecular attractive force strong. It requires more energy to disintegrate its lattice structure and convert it from solid to liquid. This property is crucial in the separation and purification process. Chemists can judge its purity by melting point measurement. The higher the purity, the closer the melting point is to the theoretical value.
Furthermore, the solubility of 4-iodo-4 '-bromobiphenyl is also worthy of attention. It has a certain solubility in common organic solvents such as chloroform and dichloromethane, but has little solubility in water. This difference in solubility is related to molecular polarity. The molecular polarity of this compound is relatively weak, and it has more affinity with non-polar or weakly polar organic solvents, while it interacts weakly with water with strong polarity. This property can be used in organic synthesis to select suitable solvents to promote the reaction or separate the product.
In addition, the density of the compound is also one of its physical properties. Although the specific value varies slightly depending on conditions, its density is indispensable for accurate measurement and reaction system design. When preparing a solution at a specific concentration or performing a liquid-liquid reaction, density data can help to accurately measure the substance and ensure the accuracy and repeatability of the experiment.
The physical properties of 4-iodo-4 '-bromobiphenyl, such as appearance, melting point, solubility and density, have a profound impact on its chemical behavior and practical application. Chemists need to consider it carefully in order to make good use of it in research and production.
