What are the physical properties of 1- [ (dichloromethylsilyl) methyl] -4-ethenylbenzene
1 - [ (dichloromethylsilyl) methyl] -4 -vinylbenzene, this is an organosilicon compound. Its physical properties are as follows:
Under normal temperature and pressure, or a colorless to light yellow liquid, clear and transparent, without visible impurities. Due to the molecular structure, silicon atoms bond with atoms such as carbon, hydrogen, and chlorine, giving the molecule a specific spatial configuration and interaction, causing it to be liquid at room temperature.
Smell its odor, or emit a weak irritating odor. Due to the presence of chlorine atoms, its chemical activity is high, and it can interact with chemical receptors in the nasal cavity, resulting in this irritating odor.
Measure its density, the relative density may be greater than that of water. This is because the relative atomic weight of silicon atoms and chlorine atoms is larger, resulting in the heavier molecular weight of the compound, and then the density is greater than that of water.
In terms of its solubility, it can be soluble in common organic solvents, such as toluene, dichloromethane, etc. Because the molecular structure of the compound has both organic groups and silicon groups, it has a certain degree of lipophilicity, which is in line with the intermolecular force of the organic solvent, so it can be miscible; however, because of its limited molecular polarity, it is difficult to dissolve in water, and the hydrogen bond between water molecules is strong, which does not match the intermolecular force of the compound.
Measure its boiling point, boiling point or in a higher temperature range. Due to the existence of van der Waals forces between molecules, and the large chemical bonds such as silicon-carbon and silicon-chlorine, higher energy, that is, higher temperature, is required to make the molecules break free from each other and boil and vaporize.
Looking at its melting point, the molecular structure is relatively regular, the intermolecular arrangement is relatively orderly, and the melting point is not too low. The specific value is determined by factors such as intermolecular forces and crystal structure.

What is the synthesis method of 1- [ (dichloromethylsilyl) methyl] -4-ethenylbenzene
To prepare 1 - [ (dichloromethylsilyl) methyl] -4 -vinylbenzene, the following method can be followed.
First take the vinyl-containing benzene derivative, often p-vinyltoluene as the starting material, because the para-vinyl group of toluene can maintain its structural characteristics in subsequent reactions, and the methyl group of toluene can provide an active check point for the introduction of silicon-containing groups.
In a suitable reaction vessel, mix p-vinyltoluene with an appropriate amount of halogenating agent, which is mostly used in dichloromethylsilane-related reagents. The reaction needs to be carried out under specific conditions, and the temperature should be controlled within a certain range, such as a mild heating state, about 50-80 degrees Celsius. This temperature range can make the reaction occur smoothly and avoid the increase of by-products caused by excessive reaction. At the same time, the addition of suitable catalysts, such as some transition metal catalysts, can effectively reduce the activation energy of the reaction, accelerate the reaction process, and enable the substitution reaction of dichloromethylsilane with the methyl group of p-vinyltoluene to occur smoothly. During the
reaction, the reaction process needs to be closely monitored. The ratio of raw materials to products can be observed by means of thin layer chromatography (TLC). When the reaction reaches the expected level, that is, the conversion rate of raw materials and the selectivity of products reach the appropriate value, the reaction will be stopped.
Then, the reaction mixture is treated. First, the product is extracted with a suitable organic solvent to separate and enrich from the reaction system. The selected organic solvent must have good solubility to the product and be easy to separate from other components in the reaction system. Then, by distillation, column chromatography and other purification methods, impurities are removed to obtain a pure 1- [ (dichloromethylsilyl) methyl] -4 -vinylbenzene product. In this way, the target product is obtained.
