This organic compound is called (4- (5-iodo-2-chlorobenzyl) phenoxy) (tert-butyl) dimethylsilane. Its chemical structure is described in the classical Chinese style of "Tiangong Kaiwu" as follows:
Looking at the structure of (4- (5-iodo-2-chlorobenzyl) phenoxy) (tert-butyl) dimethylsilane, the silicon atom first lives in the center, like the beam of a building, carrying all the parts. Silicon is connected to dimethyl, just like two wings, and the carbon and hydrogen atoms in each methyl group are connected in an orderly manner, like a row of feathers. And tert-butyl, tert-butyl is attached to silicon in the form of carbon chain branches, like a branch of the side.
Silicon is further connected to an oxygen group, which is complex with benzene ring, benzene ring, hexacarbon co-structure ring, on which hydrogen atoms are scattered, like a ring decoration. At the para-position of the benzene ring, there is a methylene group, which is then connected to another benzene ring. Above this benzene ring, there are iodine atoms at 5 positions, like pearl mosaic, and chlorine atoms at 2 positions, echoing with iodine atoms.
In this way, each atom is linked by covalent bonds and has a delicate structure, forming this unique (4- (5-iodine-2-chlorobenzyl) phenoxy) (tert-butyl) dimethylsilane chemical structure, which is like a wonderful combination of natural and artificial creations, exquisite and orderly.

What are the physical properties of (4- (5-iodo-2-chlorobenzyl) phenoxy) (tert-butyl) dimethylsilane?
(4- (5-iodine-2-chlorobenzyl) phenoxy) (tert-butyl) dimethylsilane is an organosilicon compound with unique physical properties.
Its properties are mostly colorless to light yellow transparent liquid, stable at room temperature and pressure. Due to the good chemical stability of silicon-carbon bonds, the compound is endowed with good stability and is not easy to react with common substances under normal conditions.
The boiling point is related to the intermolecular force and relative molecular weight. The compound has a large relative molecular weight, and the introduction of silicon atoms enhances the intermolecular force, resulting in a high boiling point, which is about 250-300 ° C. This property allows it to boil and vaporize at higher temperatures, and it can maintain liquid stability when applied to high-temperature treatment processes.
The melting point is determined by the degree of close arrangement and interaction of molecules. The molecular structure of the compound is complex, the arrangement is irregular, and the melting point is low, about -20-0 ° C. The lower melting point makes it easy to flow near room temperature, which is advantageous in some low-temperature operations or scenarios where materials need to be fluidized.
In terms of density, due to the large relative atomic weight of silicon atoms, the molecule contains heavy atoms such as iodine and chlorine, making it denser than water, about 1.3-1.5 g/cm ³. In applications involving liquid-liquid separation or coexistence with water, this property determines its position and behavior in the system.
In terms of solubility, it is an organosilicon compound with good fat solubility. It can be soluble in common organic solvents such as toluene, dichloromethane, tetrahydrofuran, etc. Due to the principle of similarity miscibility, these organic solvents are similar to the structure and polarity of the compound. However, it is difficult to dissolve in water because of its small overall polarity and weak interaction with water molecules. This solubility characteristic determines its dispersion and reaction in different solvent systems, providing a basis for its synthesis, separation and application.
What is the synthesis method of (4- (5-iodo-2-chlorobenzyl) phenoxy) (tert-butyl) dimethylsilane?
To prepare (4- (5-iodo-2-chlorobenzyl) phenoxy) (tert-butyl) dimethylsilane, the following method can be used.
Take 4-hydroxybenzyl alcohol first, combine it with appropriate halogenating reagents, such as thionyl chloride or phosphorus tribromide, and react under suitable reaction conditions, such as low temperature and the presence of acid binding agents, to generate 4-halobenzyl phenyl ether. This step requires attention to the precise control of the reaction temperature to avoid side reactions.
Take another 5-iodine-2-chlorobenzyl halide and combine it with the 4-halogenated benzyl phenyl ether generated above. In the presence of strong bases such as sodium hydride or potassium carbonate, in polar aprotic solvents such as N, N-dimethylformamide, nucleophilic substitution reaction is carried out. This process needs to ensure that the reaction system has no aqueous environment to prevent the failure of strong bases.
After the above reaction is completed, a (4- (5-iodo-2-chlorobenzyl) phenoxy) benzyl compound is formed, and then it is reacted with tert-butyl dimethylchlorosilane in an organic solvent such as dichloromethane in the presence of a catalyst such as imidazole or 4-dimethylaminopyridine to obtain the target product (4- (5-iodo-2-chlorobenzyl) phenoxy) (tert-butyl) dimethylsilane. This step requires attention to the amount of catalyst and the control of the reaction time to ensure that the reaction is fully carried out. During the entire synthesis process, suitable separation and purification methods, such as column chromatography or recrystallization, are required after each step of the reaction to obtain high-purity intermediate products and final products, thus ensuring the smooth progress of the synthesis.
What is the price range of (4- (5-iodo-2-chlorobenzyl) phenoxy) (tert-butyl) dimethylsilane in the market?
I have not heard the exact number of " (4- (5-iodo-2-chlorobenzyl) phenoxy) (tert-butyl) dimethylsilane" in the market price range. This compound may belong to a special silicone class and is not widely known and commonly used.
The price of various products on the market depends on the difficulty of preparation, raw material cost, demand and market competition. If the preparation of this product requires difficult methods, rare materials are used, and the demand is not wide, the price may be high. On the contrary, if the preparation is easier, the raw materials are common, the demand is still large, and the price may be moderate.
If you want to know the exact price, you should consult the supplier of chemical raw materials, the sales office of chemical reagents, or the chemical product trading platform. There are often quoted accurate prices based on real-time supply, demand and cost. Without detailed information, it is difficult to determine the price range.
