2h-benzimidazole-2-thione, 1,3-dihydro-4(or 5)-methyl-

2H-benzimidazole-2-thione, 1,3-dihydro-4 (or 5) -methyl, is a genus of organic compounds. Its chemical properties are unique and have the following characteristics:
In terms of acidity and basicity, the benzimidazole ring contains nitrogen atoms, which can exhibit weak alkalinity and can form salts with strong acids; at the same time, the sulfur atoms in the 2-thione group have lone pairs of electrons and can be used as proton receptors, showing a certain alkalinity. And the structure of 2-thione exists thiol-thione tautomerism. Under specific conditions, the tautomerism balance shifts, which affects its acidity and alkalinity.
When it comes to solubility, the substance contains a benzimidazole ring and a methyl group. It is a hydrophobic group, so its solubility in water is low; but because it contains heteroatoms such as nitrogen and sulfur, it can form intermolecular forces with some organic solvents, and has a certain solubility in polar organic solvents such as ethanol and acetone.
In terms of thermal stability, the benzimidazole ring is a conjugated system with a stable structure, giving the substance a certain thermal stability. However, at high temperatures, the 2-thione group may decompose or react, causing its structure to change.
The reactivity is quite significant. The sulfur atom of the 2-thione group is nucleophilic and can undergo nucleophilic substitution reaction with electrophilic reagents such as halogenated hydrocarbons and acyl halides to form new thioethers or thioesters. The nitrogen atom on the benzimidazole ring can also participate in the nucleophilic reaction, and the electron cloud density distribution on the ring makes the specific position prone to electrophilic substitution reaction. If it reacts with halogenating reagents under suitable conditions, the halogen atom is introduced into the benzimidazole ring. In addition, due to the existence of tautomers, the reactivity of different isomers is different, and the specific reaction conditions can promote the tautomerism to move in a direction favorable to the reaction.

The method for preparing 2-mercapto-1,3-dihydro-4 (or 5) -methylbenzimidazole is as follows:
First take an appropriate amount of o-phenylenediamine and place it in a clean reaction vessel. The o-phenylenediamine is the starting material for the reaction, and its properties are active and can undergo specific chemical reactions with the reagents added later. Then, an appropriate amount of acetic acid is added to it. Acetic acid plays both the role of solvent and reactant in this reaction. Under appropriate temperature conditions, the two are fully reacted. Temperature control is crucial, and it is generally maintained in a moderately warm state, so that the reaction can proceed smoothly without overheating. In this step, o-phenylenediamine interacts with acetic acid, and the molecular structure is rearranged and combined to preliminarily construct the basic skeleton of benzimidazole.
When the above reaction reaches a certain extent, the preliminary product has been formed in the reaction system. At this time, sulfur powder is added, and sulfur powder is the key reagent for introducing sulfhydryl groups. Then the reaction system is heated to promote the full reaction of sulfur powder and the preliminary product. Sulfur atoms are ingeniously embedded in the molecular structure, and finally 2-mercapto-1,3-dihydro-4 (or 5) -methylbenzimidazole. After the reaction is completed, appropriate separation and purification steps, such as filtration and recrystallization, are used to remove impurities and obtain a pure target product. Thus, the desired 2-mercapto-1,3-dihydro-4 (or 5) -methylbenzimidazole can be prepared.
