The synthesis method of 2% 2C5-bis (5-tert-butylbenzoxazolyl) -2-naphthol, although it is difficult to find direct records in ancient literature, can be inferred by the principle of chemical synthesis and the method of similar synthesis of predecessors.
The main points of organic synthesis are the selection of constant weight raw materials, the control of reaction conditions and the design of reaction paths. To synthesize this compound, its structure can be reviewed first. This compound contains a naphthol skeleton, with specially substituted benzoxazolyl groups connected on both sides.
The raw material is selected, and naphthol can be regarded as the starting material of the core structure. Naphthol has a wide source and stable properties, which can be used as the basis for the construction of this complex molecule. The introduction of 5-tert-butyl benzoxazolyl requires suitable reagents. Or halogenates containing tert-butyl and benzoxazole structures, such as 5-halo-tert-butyl benzoxazole, have higher halogen atom activity, which is conducive to subsequent nucleophilic substitution reactions.
In terms of reaction pathways, nucleophilic substitution is a feasible strategy. The phenolic hydroxyl group of naphthol has a certain nucleophilic property. Under basic conditions, the phenolic hydroxyl group can be converted into phenoxy anions, and the nucleophilic activity is greatly increased. At this time, 5-halo-tert-butyl benzoxazole is added, the phenoxy anion attacks the carbon attached to the halogen atom of the halogen, and the halogen ion leaves, forming a carbon-oxygen bond, and realizing the connection of 5-tert-butyl benzoxazole based on naphthol.
The reaction conditions are also critical. The choice of base is very important, such as weak bases such as potassium carbonate and sodium carbonate, or strong bases such as sodium hydride, depending on the reactivity requirements. The choice of solvent also affects the reaction process. Polar aprotic solvents such as N, N-dimethylformamide (DMF), dimethyl sulfoxide (DMSO), etc. can promote interionic reactions and facilitate nucleophilic substitution. The reaction temperature needs to be carefully controlled. If the temperature is too low, the reaction rate will be slow; if the temperature is too high, it may cause side reactions to breed. Generally, the reaction can be initiated at low temperature first, and then moderately heated to accelerate the reaction. The reaction process can be monitored by means of thin layer chromatography (TLC), and the reaction can be stopped in time to purify the product. In this way, 2% 2C5-bis (5-tert-butylbenzoxazolyl) -2-naphthol can be obtained.

Today, there are 2,5-bis (5-tert-butylbenzoxazolyl) -2-octyne in the market. What is its price?
The 2,5-bis (5-tert-butylbenzoxazolyl) -2-octyne is a compound that has attracted much attention in the field of organic synthesis. Its price range is difficult to generalize, because it is subject to many factors.
First, purity is the key. If the purity is extremely high, almost 99% or more, it is suitable for high-end scientific research experiments, precision organic synthesis and other fields, and its price is high. The price per gram may reach hundreds or even thousands of yuan. Due to the preparation of such high-purity products, complex purification processes are required, which increases the cost significantly.
Second, market supply and demand also affect the price. If for a while, many scientific research institutions and enterprises have strong demand for it, but the supply is limited, the price will rise. On the contrary, if the supply exceeds the demand, the price will tend to drop.
Third, the difficulty of the preparation process is related to the cost and price. If the preparation of this compound requires scarce raw materials, special reaction conditions or lengthy steps, the cost will be high, and the price will also increase.
Roughly speaking, the price per gram of ordinary purity (about 95%) may be around tens of yuan to hundreds of yuan. If the purity is higher, it is also common for the price to climb to several hundred yuan per gram. However, this is only an estimate, and the actual price is subject to real-time market conditions.
