2-chloro-5-methylbenzene-1, what are the synthesis methods of 4-diamine?
There are various ways to synthesize 2-chloro-5-methylbenzene-1,4-diamine, which are described in detail by you below.
First, it can be prepared by reduction of the corresponding nitro compound. First, the nitro group is introduced through nitration reaction with suitable raw materials. For example, with 2-chloro-5-methyltoluene as the starting material, under appropriate nitrification conditions, such as in the mixed acid system of nitric acid and sulfuric acid, the reaction temperature, time and other factors are controlled to introduce nitro groups into the benzene ring at specific positions to generate 2-chloro-5-methyl-1,4-dinitrobenzene. Subsequently, the dinitro compound is reduced. There are many reduction methods, such as catalytic hydrogenation. In the presence of suitable catalysts, such as palladium carbon, platinum carbon, etc., hydrogen is introduced, and the nitro group can be gradually reduced to an amino group under a certain temperature and pressure, so as to obtain the target product 2-chloro-5-methylbenzene-1,4-diamine. The advantage of this method is that the reaction is relatively clean and the atomic utilization rate is high, but the reaction equipment is relatively high, and a suitable hydrogenation device is required.
Second, halogenation can be combined with aminolysis. First, chlorine atoms are introduced into the benzene ring to determine the substitution position of chlorine, and then ammonia or amine reagents are used to replace the halogen atoms at specific positions with amino groups. For example, with suitable benzene derivatives, chlorine atoms are introduced at specific positions through halogenation to obtain chlorine-containing intermediates. Afterwards, under appropriate reaction conditions, such as suitable solvents, temperatures, pressures, and catalysts, ammonia or amines are reacted with ammonia or amines to gradually introduce amino groups. This method can flexibly control the order and location of substituents, but attention should be paid to the precise control of reaction conditions to ensure the selectivity and yield of the reaction.
Third, diazotization and related conversion reactions can also be used. First, the intermediate containing amino group is prepared, the amino group is converted into diazonium salt, and then through the specific reaction of diazonium salt, chlorine atoms and methyl groups are introduced, and after a series of reactions, 2-chloro-5-methylbenzene-1,4-diamine is obtained. This method has relatively many steps and needs to strictly control the diazotization reaction and subsequent conversion reaction conditions. However, it has unique advantages for the construction of specific structures, and can achieve some substituent positions and structural requirements that are difficult to achieve by other methods.
Different synthesis methods have their own advantages and disadvantages. In practical applications, many factors such as raw material cost, difficulty of reaction conditions, product yield and purity need to be comprehensively considered to choose the most suitable synthesis path.
