The synthesis of 2-bromo-5-benzoylthiophene is a very important topic in the field of organic synthesis. There are several common synthesis routes.
First, the thiophene ring can be halogenated through the thiophene derivative as the starting material, and bromine atoms can be introduced. This halogenation reaction is usually carried out under suitable reaction conditions with suitable halogenating reagents, such as bromine, N-bromosuccinimide (NBS), etc. Taking NBS as an example, it is often used in organic solvents such as carbon tetrachloride, under the action of initiators such as benzoyl peroxide, heating or lighting initiates the reaction, thereby introducing bromine atoms at specific positions in the thiophene ring to obtain bromothiophene derivatives.
Then, the resulting bromothiophene-containing derivative is acylated to introduce a benzoyl group. This acylation reaction generally uses Friedel-Crafts acylation reaction. Benzoyl chloride is used as the acylation reagent, and the reaction is carried out in a suitable organic solvent such as dichloromethane under the catalysis of Lewis acid catalysts such as anhydrous aluminum trichloride. During the reaction, attention should be paid to controlling the reaction temperature and the ratio of reactants to avoid side reactions. In this way, 2-bromo-5-benzoylthiophene can be synthesized.
Second, benzoic acid derivatives can also be achieved through specific coupling reactions with bromothiophene-containing related reagents. For example, using palladium-catalyzed cross-coupling reactions, such as Stille coupling reaction, Suzuki coupling reaction, etc. Taking Stille coupling reaction as an example, bromothiophene derivatives need to be reacted with organotin reagents (containing benzoyl-related structures) under the catalysis of palladium catalysts such as tetra (triphenylphosphine) palladium, etc., in the presence of suitable reaction solvents and bases. Through careful regulation of the reaction conditions, the target product 2-bromo-5-benzoylthiophene can also be successfully synthesized. This method requires stricter reaction conditions, and the anhydrous and anaerobic environment of the reaction system needs to be strictly controlled to ensure the smooth progress of the reaction.

2-Bromo-5-benzoylthiophene is one of the organic compounds. It has specific physical properties and is widely used in the field of organic synthesis.
Looking at its physical properties, at room temperature, this substance is often in a solid state, either powdery or crystalline state, depending on the specific preparation conditions and purity. Its melting point is about [X] ° C, which can vary slightly due to the presence of impurities.
As for the boiling point, at normal pressure, it is about [X] ° C. However, it should be noted that because the compound is sensitive to heat and may decompose at high temperature, the determination of the boiling point often needs to be carried out under reduced pressure, so a more accurate value can be obtained.
In terms of solubility, 2-bromo-5-benzoylthiophene has good solubility in organic solvents. Such as common dichloromethane, chloroform, tetrahydrofuran, etc., can be used as its good solvent. This property is very critical in the operation of organic synthesis reactions and the separation of products. Because it can fully mix the reactants, accelerate the reaction process, and facilitate subsequent extraction, recrystallization and other separation and purification steps.
Furthermore, the compound has certain stability. However, in its molecular structure, bromine atoms and benzoyl groups are active check points, and under specific conditions, they can participate in a variety of chemical reactions, such as nucleophilic substitution reactions, oxidation reactions, etc. This also makes it an important intermediate for the synthesis of more complex organic compounds.
In summary, the physical properties of 2-bromo-5-benzoylthiophene, such as solid form, specific melting point, boiling point and solubility, have a profound impact on its application in the field of organic synthesis.

2-Bromo-5-benzoylthiophene is one of the organic compounds. Its chemical properties are very interesting, let me explain in detail.
In this compound, the bromine atom and the benzoyl group are respectively connected to the specific position of the thiophene ring, which gives it unique chemical activity. First of all, the bromine atom has strong electronegativity, which changes the local charge distribution of the molecule, which affects the electron cloud density of the ortho and para sites. In the nucleophilic substitution reaction, the bromine atom is easily replaced by the nucleophilic reagent. For example, in the alkali environment, the hydroxyl negative ion, as the nucleophilic reagent, can react with the bromine atom to generate the corresponding hydroxyl substitution product.
And benzoyl, containing carbonyl structure, carbonyl carbon is electrophilic. This makes 2-bromo-5-benzoylthiophene able to participate in many reactions involving carbonyl groups. For example, under acid catalysis with alcohols, condensation reactions can occur to form acetal structures. And the conjugated system of benzoyl groups also plays a role in the electron cloud of thiophene ring, affecting its aromaticity and reactivity.
The thiophene ring itself is a five-membered heterocycle and has aromaticity, but its electron cloud distribution is slightly different from that of benzene, and the electron cloud is more biased towards sulfur atoms. This property interacts with bromine atoms and benzoyl groups, making 2-bromo-5-benzoylthiophene exhibit unique selectivity in various reactions. In some electrophilic substitution reactions, the reaction check point is specific due to the localization effect of bromine atoms and benzoyl groups.
2-bromo-5-benzoylthiophene has a wide range of uses in the field of organic synthesis due to these chemical properties. It can be used as a key intermediate for the preparation of more complex organic compounds, providing an important foundation for many aspects of organic chemistry research and drug synthesis.

2-Bromo-5-benzoylthiophene is in the market, and the range of its price is difficult to determine. This is due to the influence of various factors, resulting in unstable price fluctuations.
Looking at past transactions, the price of chemical raw materials often varies depending on the state of supply and demand. If there is a large demand for this product, but the supply is small, the price will increase; conversely, if the supply exceeds the demand, the price may decrease.
The difficulty of its preparation is also the main reason. If the preparation method is difficult, and various reagents and exquisite processes are required, the cost will be high, and the price will be expensive. On the contrary, the preparation method is simple, and the price may be slightly lower.
Furthermore, the competitive situation of the market also affects its price. If there are many producers of this product, they compete with each other, or cut prices for the market; if there are few producers and they are almost monopolized, the price may remain high.
And the price of raw materials is also the key. The system of 2-bromo-5-benzoylthiophene depends on other raw materials, and the price of raw materials will change.
Overall, in order to determine the range of the intermarket price of 2-bromo-5-benzoylthiophene, it is necessary to provide information on the market situation, and carefully observe the changes in supply and demand, preparation, competition, raw material prices, and other factors. However, it is difficult to determine the exact price range at this moment.
