What are the synthesis methods of 4,4 '-diiodo-p-terphenyl?

The synthesis method of 4,4 '-diiodine p-terphenyl, described in ancient books, is a multi-step chemical synthesis path.
First, with p-terphenyl as the initial material, it can be prepared by halogenation reaction. Among them, the choice of halogenating reagents is very critical. Iodine is often used as a halogen source, supplemented by appropriate catalysts, such as under the catalysis of Lewis acid, iodine reacts with p-terphenyl. Lewis acid can activate iodine molecules, enhance their electrophilic ability, and promote the reaction to occur more easily. This process requires temperature control and control. When the temperature is too high or too long, it is easy to cause the formation of polyhalogenated by-products and affect the purity of the target product.
Second, synthesized by Suzuki reaction. The aromatic derivatives containing iodine and p-terphenylboronic acid derivatives are first prepared, and the two react in palladium catalysts, bases and appropriate solvent systems. Palladium catalysts have a great impact on the reactivity. Common palladium catalysts such as tetra (triphenylphosphine) palladium, etc. The type and dosage of bases are also related to the reaction process, and inorganic bases such as potassium carbonate and sodium carbonate are commonly used. The advantage of this method is that it has good selectivity and can accurately synthesize the target product, but the preparation of raw materials is relatively complicated and the cost is high.
Third, through the Grignard reaction path. First, the halogenated aromatic Grignard reagent containing iodine is prepared, and then it reacts with the corresponding halogenated p-terphenyl derivatives. The preparation of Grignard reagents requires an anhydrous and oxygen-free environment, and the operation Reaction conditions such as temperature, solvent properties, etc., have a significant impact on the yield and purity of the product. Anhydrous ether or tetrahydrofuran are commonly used as solvents, and the reaction temperature needs to be carefully adjusted according to the specific characteristics of the reactants.

What is the price range of 4,4 '-diiodo-p-terphenyl in the market?

I have never heard of "4%2C4%27%27-diiodo-p-terphenyl" at the market price. This name is rather uncommon, or it is a specific chemical substance, which is not widely known and commonly used. If you want to know its price, you should consult a special chemical material trading venue or a chemical product website.
Or there is a chemical company that specializes in the sale of such chemicals. You can visit the other place and ask the shopkeeper and partner to find out the approximate price. Or on the chemical e-commerce platform, search for its entry, and observe the price marked by various companies to indicate its price range.
However, the price of these specific chemicals often varies due to changes in quality, purity, source of supply, and market supply and demand. The purity is high, the price may be high; when the supply is tight, the price also tends to rise. Therefore, it is difficult to determine the certain price range, and it must be investigated on the spot and in real time.
