Benzothiazole, 2-indol-3-yl- (8CI)

Alas! There is a chemical substance called Benzothiazole, 2-indol-3-yl - (8CI). To know its chemical structure, please listen to me in detail.
The structure of this compound contains the part of benzothiazole. The benzothiazole is formed by fusing the benzene ring with the thiazole ring. The benzene ring is a six-membered carbon ring with a conjugated system and a planar structure. The carbon atoms on it are connected to each other by covalent bonds, and each carbon atom has a p-electron that does not participate in the conjugation, which together forms a large π bond, giving the benzene ring special stability. The thiazole ring is a five-membered heterocycle containing sulfur and nitrogen. Sulfur and nitrogen atoms occupy specific positions in the ring. Due to their electronegativity, which is different from that of carbon atoms, the distribution of electron clouds in the ring is uneven, which affects the chemical properties of compounds.
Furthermore, there is a 2-indol-3-yl-part in its structure. The indole ring is also an important structural unit, which is formed by fusing the benzene ring with the pyrrole ring. In 2-indol-3-yl-there are specific substituents at the 2nd and 3rd positions of the indole ring. The pyrrole ring is a nitrogen-containing five-membered heterocyclic ring, and the solitary pair electrons of the nitrogen atom participate in the intra-ring conjugation, so that the indole ring also has certain stability and unique electronic properties.
The structure of this compound, the interaction of various parts, benzothiazole and 2-indol-3-yl-are connected by chemical bonds to construct a unique spatial configuration and electron cloud distribution, which in turn determines its physical and chemical properties. It may have important uses in organic synthesis, drug research and development and other fields.

Benzothiazole-2-indole-3-yl (8CI) has a variety of physical properties. The appearance of this compound may be in a specific form, but its exact appearance varies depending on the preparation and environment, or it is crystalline, the texture may be delicate and have a regular geometric shape, or it may have a unique luster under light, or it may be powdery, and the particle thickness varies.
Its melting point is one of the key physical properties. The exact melting point fluctuates slightly due to different experimental conditions and purity. It is roughly within a certain temperature range. When the melting point is reached, the compound gradually melts from a solid state to a liquid state. This process requires heat absorption to overcome intermolecular forces. In terms of boiling point, under a specific pressure, the compound will boil and transform into a gaseous state. This temperature reflects the energy required for the molecule to break away from the condensed state, which is of great significance to its state and application under different temperature environments.
Solubility is also important. In organic solvents, such as common ethanol, acetone, dichloromethane, etc., the solubility may vary. In ethanol, it may exhibit a certain solubility and form a uniform solution, indicating that specific interactions can be formed between molecules and ethanol molecules. In water, due to the difference in polarity between the compound structure and the water molecule, the solubility may be extremely low or even insoluble, and it is dispersed or floated on the water surface as tiny particles.
Density is related to the unit volume mass, and its value reflects the degree of compactness of molecular accumulation. It is crucial for applications involving mixing, separation, and distribution in specific systems. In addition, the stability of the compound is also an important physical property. Under normal temperature, light and general chemical environment, or with a certain stability, the molecular structure is not easy to change significantly; but when exposed to high temperature, strong light or specific chemical reagents, or cause chemical reactions to cause structural changes. In short, these physical properties of benzothiazole-2-indole-3-yl (8CI) have far-reaching implications for its applications in chemical synthesis, materials science, drug development and other fields.

The common preparation routes of benzothiazole-2-indole-3-yl (8CI) are as follows:
First, use o-aminothiophenol and the corresponding indole-3-formaldehyde as raw materials. In a suitable reaction vessel, mix o-aminothiophenol and indole-3-formaldehyde in an appropriate ratio, and use an appropriate amount of acid or base as catalyst, such as acetic acid, pyridine, etc. At a suitable temperature, it is usually heated and refluxed for several hours. During this process, the amino group of o-aminothiophenol and the aldehyde group of indole-3-formaldehyde first undergo a condensation reaction to form an imine intermediate, followed by imine cyclization. After a series of electron rearrangements and chemical bonds are broken and formed, the target product benzothiazole-2-indole-3-yl is finally formed. After the reaction is completed, a relatively pure product can be obtained by conventional separation and purification methods, such as extraction, column chromatography, etc.
Second, benzothiazole-2-halide and indole-3-boronic acid are used as starting materials. In the reaction system of an inert gas atmosphere, the two are mixed with an appropriate amount of palladium catalyst (such as tetrakis (triphenylphosphine) palladium, etc.), a base (such as potassium carbonate, etc.) and a suitable solvent (such as toluene, dioxane, etc.). The reaction is stirred at a certain temperature for several hours, and the reaction follows the coupling mechanism catalyzed by palladium. The halogen atom of benzothiazole-2-halide is coupled with the boron group of indole-3-boronic acid to construct the benzothiazole-2-indole-3-based structure. After the reaction is completed, the product can be purified by vacuum distillation and recrystallization.
Third, using benzothiazole derivatives and indole derivatives containing appropriate substituents as raw materials, under the catalysis of strong Lewis acid (such as aluminum trichloride, etc.), in a specific solvent (such as dichloromethane, etc.), the reaction is reacted at low temperature to room temperature. This reaction promotes the electrophilic substitution reaction of benzothiazole derivatives and indole derivatives with the help of Lewis acid activation of substrate molecules, and gradually generates benzothiazole-2-indole-3-yl. After the reaction is completed, the reaction mixture is processed through neutralization, washing, drying and other steps, and then the target product is obtained.

There are various methods for preparing 2-indole-3-ylbenzothiazole (Benzothiazole, 2-indol-3-yl - (8CI)) in the past. First, it can be formed by condensation reaction of indole and benzothiazole derivatives under the action of a specific catalyst with an appropriate solvent. The reaction conditions are quite critical, and the temperature needs to be controlled in a suitable range, and the amount of catalyst is also exquisite. At least the reaction is slow, and at most it may increase the side reactions.
Second, using benzothiazole as the starting material, halogenated benzothiazole is obtained by halogenation reaction, and then nucleophilic substitution is carried out with indole derivatives in an organic solvent in the presence of bases. In this process, the type and dosage of bases, as well as the polarity of the organic solvent, all have a great influence on the reaction. If the base is too strong, the indole structure may be damaged; the polarity of the organic solvent may be improper, or the reaction may be difficult to proceed smoothly.
Third, or a series reaction route can be designed. First, the indole is reacted with a sulfur-containing reagent to construct a sulfur-containing intermediate, and then cyclized to form a benzothiazole structure, thereby obtaining the target product. This route requires precise control of the process and conditions of each step of the reaction in order to improve the yield and purity of the product. The time, temperature, and proportion of reactants of each step need to be carefully adjusted, and it is difficult to achieve the expected effect if there is a slight difference.
