What is the chemical structure of 2- (4-fluorophenyl) -5- (5-iodo-2-methylbenzyl) thiophene?

2-%284-fluorophenyl%29-5-%285-iodo-2-methylbenzyl%29thiophene is the English name of an organic compound, which is converted into Chinese, that is, 2- (4-fluorophenyl) -5- (5-iodine-2-methylbenzyl) thiophene. The chemical structure of this compound is as follows:

Its core structure is a thiophene ring, which is a five-membered heterocycle composed of four carbon atoms and one sulfur atom, and has aromatic properties.

At position 2 of the thiophene ring, a 4-fluorophenyl group is connected. This 4-fluorophenyl group, that is, the position 4 on the benzene ring, is replaced by a fluorine atom. The benzene ring is a six-membered carbon ring with conjugated system and aromatic properties. The introduction of fluorine atoms will affect the electron cloud distribution of the benzene ring due to the large electronegativity of fluorine, which in turn affects the electronic properties and reactivity of the whole compound.

At position 5 of the thiophene ring, 5-iodine-2-methylbenzyl is connected. The benzyl structure is benzyl, that is, the benzene ring is connected to a methylene (-CH ² -). Here, the position 5 of the benzene ring is replaced by an iodine atom, and the position 2 is replaced by a methyl group. Iodine atoms are large in size and have certain electron-withdrawing properties; methyl is the power supply group. The substitution of the two in different positions of the benzene ring will change the electron cloud density distribution of the benzene ring, and at the same time affect the steric resistance and electronic effects of the whole group after the benzyl group is connected to the thiophene ring.

In the structure of this compound, different substituents are connected by covalent bonds, and each part interacts with each other to jointly determine the physical and chemical properties of the compound, such as melting point, boiling point, solubility, reactivity, etc., which may have important uses and research value in organic synthesis, pharmaceutical chemistry and other fields.

What are the physical properties of 2- (4-fluorophenyl) -5- (5-iodo-2-methylbenzyl) thiophene?

2-%284-fluorophenyl%29-5-%285-iodo-2-methylbenzyl%29thiophene, this is an organic compound, according to the method of "Tiangong Kaiwu", its physical properties should be described in detail in ancient sayings.

This compound, looking at its appearance, under room temperature, or a solid state, like crystalline, fine or fine, white or slightly yellowish, like jade with light, standing in the vessel, there is a faint light flow, as if it contains the spirit of nature.

On its melting point, after careful measurement, it can reach a specific temperature value, just like ice melting in the spring sun, to a certain degree of warmth, from solid to liquid, this temperature is its inherent nature, just like human nature, unique and unchanged. Its boiling point is also the key physical property. When heat energy is applied and the corresponding high temperature is reached, the compound will be like a mist of transpiration and turn into gaseous ascension. This boiling point value is like the boundary of its sublimation, indicating the degree of transformation.

Speaking of solubility again, in organic solvents, it may have different performance. In alcohol solvents, it may be slightly soluble, just like snowflakes falling on warm wine, which melt briefly, but it is difficult to completely dissipate; in ether solvents, its solubility may be enhanced, like a fish getting water, gradually melting in it, and the solution is clear, as if it were one. In water, its solubility is very small, just like oil floating in water, and the two are difficult to blend. This is because the compounds and water are contrary to each other, just like yin and yang, and each follows its own path. If the density is greater than that of water, it is placed in water, such as a stone sinking into the abyss, quietly sinking, hidden in the bottom of the water; if it is less than water, it is like a wood floating in waves, leisurely floating on the water surface. The difference in density is also a representation of its physical properties, which is essential in the art of identification and separation.

As for its volatility, under normal temperature and pressure, the volatility may not be very significant, but in a warm environment, it may gradually appear to evaporate, just like the fragrance of flowers, slowly dispersing in the surrounding space. Although it is invisible and colorless, it can be sensed by smell. This volatility is also one end of its physical properties, which is related to its preservation and use.
