What are the physical properties of 5-bromo-1-methyl-1H-benzo [d] imidazole?
5-% ether-1-methyl-1H-indolo [d] -azole This substance has different properties. Looking at its structure, the shape of the five-membered indolo-azole, the five-membered nitrogen-containing heterocycle is combined with the azole, and the methyl is based on one, this structure makes it specific.
On its physical rationality, under normal conditions, it is a crystalline body, its color is either white or nearly colorless, like the purity of snow, and the purity of ice. Its melting point, after research, is about a specific temperature range, which is crucial for identification and purification. Because of its crystalline structure, the intermolecular force is fixed, and the melting point can be measured and accurate.
Its solubility, in organic solvents, such as ethanol, chloroform, etc., is soluble and melted, just like fish get water, and they blend seamlessly. However, in water, it is insoluble, and the polarity of water and the non-polarity of the structure of the substance make the two repellent and difficult to mix. This solubility is a consideration when separating, extracting and preparing.
And its boiling point, under a certain pressure, reaches a certain value and boils. The state of gasification, the molecule breaks free from binding and escapes in the air. This boiling point is also a characteristic of its physical properties and is related to operations such as distillation, which can separate the substance from other substances to obtain a pure substance. < Br >
Furthermore, its density, compared with water, is either light or heavy. If it is lighter than water, it will float on the surface of the water, like a boat on the water; if it is heavier than water, it will sink to the bottom of the water, like a stone falling into an abyss. This density property, in a mixed system, can help to judge the distribution of substances and is also the basis for studying their physical behavior.
What are the chemical properties of 5-bromo-1-methyl-1H-benzo [d] imidazole
The chemical properties of 5-% hydroxyl-1-methyl-1H-indolo [d] imidazole are as follows:
This compound has a certain alkalinity, because it contains nitrogen atoms, and the lone pair electrons on the nitrogen atom can bind protons. In acidic media, corresponding salts may be formed, which affects its solubility and reactivity. The conjugate system of its indole ring and imidazole ring endows the compound with certain stability and special electronic properties. The conjugate structure can delocalize the electron cloud, make the molecule more stable, and affect its spectral properties. For example, there are specific absorption peaks in the ultraviolet-visible spectrum, which can be used for qualitative and quantitative analysis.
According to the electrophilic substitution reaction, some positions on the indole ring and imidazole ring of the compound have high electron cloud density and are vulnerable to electrophilic attack. Generally speaking, the electron cloud density of the 3-position of the indole ring and the 5-position (relative number) of the imidazole ring is high, and electrophilic substitution may occur preferentially, such as halogenation, nitrification, sulfonation and other reactions. Electrophilic reagents will selectively attack these check points with high electron cloud density to generate corresponding substitution products.
This compound may also participate in some cyclization reactions. Due to the multiple active check points and appropriate spatial structures in the molecule, under certain conditions, new cyclic structures may be formed through intramolecular reactions, further enriching its chemical diversity.
In redox reactions, the conjugated system or nitrogen-containing heterocyclic ring of the compound can be used as an electron receptor or donor. In case of suitable oxidants, oxidation reactions may occur, such as the oxidation of unsaturated bonds on the ring, or the change of the oxidation state of the nitrogen atom; in case of reducing agents, electrons may be accepted for reduction reactions, such as the hydroreduction of unsaturated bonds. < Br >
In the interaction with metal ions, the lone pair electrons on the nitrogen atom can form coordination bonds with metal ions as ligands to form metal complexes, which may have potential applications in catalysis, materials science and other fields.
What is the synthesis method of 5-bromo-1-methyl-1H-benzo [d] imidazole?
To prepare 5-% ether-1-methyl-1H-indoleo [d] -azole, the following ancient method can be used.
First take the appropriate starting material, usually with a specific substituent indole derivative as the base. The selection of this derivative is related to the direction of the reaction and the purity of the product, and needs to be carefully selected.
In the reactor, add an appropriate amount of reagent and solvent. The properties of the solvent ensure that the raw material and the reagent can be well soluble and do not disturb the reaction process. Common organic solvents such as dichloromethane, N, N-dimethylformamide, etc., are carefully determined according to the needs of the reaction. < Br >
Add a condensing agent, such as dicyclohexyl carbodiimide (DCC) or 1-ethyl-3- (3-dimethylaminopropyl) carbodiimide hydrochloride (EDC · HCl), to promote the condensation reaction between molecules. The amount of condensing agent, when precisely controlled, will slow down the reaction at least, and increase impurities at most.
Warm up to a suitable temperature, which varies depending on the reaction characteristics. Or at room temperature, or need to be heated to tens of degrees Celsius. The heating process should be done slowly, and close attention should be paid to the changes in the reaction system to avoid the reaction being out of control due to sudden temperature changes. < Br >
During the reaction period, the reaction progress was checked by thin layer chromatography (TLC). When the raw material point gradually fades, the product point is clearly identifiable and no longer changes, indicating that the reaction is nearly complete.
After the reaction is completed, pour the reaction solution into an appropriate amount of quenching agent to stop the reaction. The common quenching agent is water or dilute acid solution. During operation, it should be added slowly and stirred at the same time to prevent local overheating or violent reaction.
Then, the separation and purification technique is performed. First, by extraction method, the product is enriched in the organic phase by using a suitable organic solvent and the aqueous phase for many times. Then, by column chromatography, appropriate silica gel and eluent are selected to further purify the product, remove its impurities, and obtain pure 5-% ether-1-methyl-1H-indolo [d] -azole.
Each step of operation requires fine, and a slight difference may affect the quality and quantity of the product. From raw material selection to product production, it all depends on the skills and focus of the operator.
