Ethyl 2-iodo-5-methylbenzoate

Ethyl 2-iodo-5-methylbenzoate, the Chinese name for ethyl 2-iodo-5-methylbenzoate, can be deduced in the following way.
First, "benzoate" indicates that this compound is a benzoate, the basic benzoate of benzoic acid is connected to a carboxyl group ($C_6H_5COOH $). "Ethyl" represents ethyl, that is, the carboxyl group ($-OH $) is replaced by ethoxy ($- OCH_2CH_3 $) to form $C_6H_5COOCH_2CH_3 $.
And the substituent on "2-iodo-5-methyl" is described. " 2-Iodo "means that there is an iodine atom ($-I $) substituted at the first position (2-carbon) of the carbon atom of the benzene carboxyl phase (1-carbon);" 5-methyl "means that there is a methyl ($- CH_3 $) substituted at the second position (5-carbon) of 1-carbon.
Therefore, Ethyl 2-iodo-5-methylbenzoate is used: On benzene, 1-carbon is connected to $COOCH_2CH_3, 2-carbon is connected to an iodine atom, and 5-carbon is connected to a methyl group. In the chemical formula, it is approximately $C_9H_9IO_2 $. In its complete form, the six carbon atoms of benzene are interconnected with each other in a common form, and each substituent is interconnected with the benzene at the above position. In this case, the co-relationship between the carbon oxides and benzene of the ethyl ester group can give a certain degree of chemical activity and physical rationality of the compound. The iodine atom is also affected by the reaction activity and properties of the compound due to its atom semi-large and low-density properties. The methyl group changes the density of the sub-cloud on the benzene, which affects the integrity of the compound.

There are several common methods for preparing Ethyl 2-iodo-5-methylbenzoate (2-iodo-5-ethyl methylbenzoate).
One of them can be started from 2-methylbenzoic acid. First, 2-methylbenzoic acid and ethanol are esterified under the catalysis of concentrated sulfuric acid to form 2-ethyl methylbenzoate. This reaction needs to be carried out under heating conditions, and concentrated sulfuric acid acts as both a catalyst and a water absorption effect to promote the reaction to move in the direction of ester formation. Then, ethyl 2-methylbenzoate is iodized. Ethyl 2-iodo-5-methylbenzoate can be obtained by oxidizing iodine to a positive iodine ion with higher activity by hydrogen peroxide and introducing an iodine atom at the 2-position of the benzene ring.
Second, ethyl 5-methyl-2-nitrobenzoate can be obtained from 5-methyl-2-nitrobenzoate. First, ethyl 5-methyl-2-nitrobenzoate is reduced under acidic conditions with iron powder or zinc powder to transform the nitro group into an amino group to obtain ethyl 5-methyl-2-aminobenzoate. Then, 5-methyl-2-aminobenzoate ethyl ester is diazotized with sodium nitrite in hydrochloric acid solution to form a diazonium salt. After that, in the presence of potassium iodide, the diazonium group is replaced by an iodine atom to obtain the target product Ethyl 2-iodo-5-methylbenzoate.
Third, 2-bromo-5-methylbenzoate ethyl ester is used as the raw material. Ethyl 2-iodo-5-methylbenzoate was obtained by palladium-catalyzed halogen exchange reaction, using potassium iodide as the iodine source, heating the reaction in the presence of appropriate ligands (such as tri-tert-butylphosphine, etc.) and bases (such as potassium carbonate), so that the bromine atom was replaced by the iodine atom to obtain Ethyl 2-iodo-5-methylbenzoate. This method requires attention to the control of reaction conditions to ensure the activity of the palladium catalyst and the smooth progress of the reaction.

Ethyl 2-iodo-5-methylbenzoate (ethyl 2-iodo-5-methylbenzoate) is also an organic compound. Its physical properties are quite impressive.
Looking at its properties, it is mostly liquid at room temperature. Due to the characteristics of its molecular structure, the intermolecular force is not strong enough to condense into a solid state. Its color is colorless and transparent, or slightly yellowish, such as the morning light pouring on the clear liquid, with a slightly yellowish rhyme in the clarity.
When it comes to the boiling point, due to the structure of benzene ring, ester group and iodine atom in the molecule, the interaction is complex, and the boiling point is in a certain range, about a relatively high temperature. Because more energy is required to overcome the intermolecular forces, the liquid state is converted to a gaseous state.
As for the melting point, it is relatively low, because the molecular arrangement is not highly regular, the lattice energy is limited, and the transformation between solid and liquid state is easier.
Its density also has characteristics, which is heavier than water, so if it is mixed with water, it often sinks underwater, like a pearl falling into a deep pool. In terms of solubility, the compound is quite miscible in organic solvents such as ethanol and ether. Due to the principle of "similar miscibility", the polarity of its molecules is similar to that of organic solvents and can be miscible with each other. However, in water, its solubility is poor. Because the overall polarity of the molecule is limited, it is difficult to fuse with water molecules with extremely strong polarity, just like the difficulty of mixing oil and water.
Its refractive index is also one of the unique physical properties. When light passes through this compound, it is refracted to a specific degree, as if light is meandering in a unique path, reflecting the influence of its internal structure on light propagation.
In summary, the physical properties of Ethyl 2-iodo-5-methylbenzoate are determined by its molecular structure, and each property is interrelated, which is of great significance in the research and application of organic chemistry.
