    What are the synthesis methods of 4- (4-phenylphenyl) iodobenzene?
    There are many ways to synthesize 4- (4-phenylphenyl) iodobenzene. First, it can be achieved through a palladium-catalyzed cross-coupling reaction. Iodobenzene and 4-phenylboronic acid are taken as raw materials, in the presence of palladium catalysts such as tetra (triphenylphosphine) palladium [Pd (PPh 🥰) ], with potassium carbonate as a base, in a mixed solvent of organic solvents such as dioxane and water, heating and stirring the reaction. In this process, the palladium catalyst activates iodobenzene and boric acid to promote the coupling of the two to form the target product 4- (4-phenylphenyl) iodobenzene.
    Second, the Ullmann reaction can be used. Iodobenzene and 4-iodobiphenyl are used as starting materials, copper powder or cuprous iodide catalyst is added, potassium carbonate is used as base, and high-boiling organic solvent such as N, N-dimethylformamide (DMF) is refluxed at high temperature. In this reaction, the copper catalyst promotes the coupling of two molecules of halogenated aromatics to obtain 4- (4-phenylphenyl) iodobenzene.
    Furthermore, the reaction can be reacted with the help of Grignard reagents. 4- (4-phenylphenyl) iodobenzene can also be formed by reacting 4-bromobiphenyl with iodobenzene in an organic solvent such as anhydrous ether or tetrahydrofuran under the action of a suitable catalyst such as nickel catalyst.

As for air, oxygen can cause oxidation and deteriorate 4- (4-phenylphenyl) iodobenzene, so make sure that the storage container is well sealed, and it is best to fill it with inert gases such as nitrogen to isolate the air. In addition, temperature is also critical, and high temperature will accelerate its decomposition rate. It should usually be placed in a low-temperature environment, such as a refrigerator freezer, and the temperature should be maintained at 2-8 ° C.
    Besides transportation, because of its certain chemical activity, the packaging must be stable. Appropriate packaging materials should be used to ensure that the packaging is not damaged due to vibration and collision during transportation. And the transportation environment should also be paid attention to. It is necessary to avoid high temperature and strong light. It is advisable to choose a cool and shaded transportation vehicle. At the same time, the transportation personnel should also be familiar with its chemical properties and emergency treatment methods to prevent accidents from happening. In short, the storage and transportation of 4- (4-phenylphenyl) iodobenzene, shading, sealing, temperature control, and stable packaging and personnel awareness characteristics are all essential points.
    What is the market price of 4- (4-phenylphenyl) iodobenzene?
