To synthesize 2,3-dihydro-1-methyl-4- (trifluoromethyl) naphthalene, there are various methods. To cover the process of organic synthesis, many methods are often relied on to achieve its work.
First, the method of nucleophilic substitution can be borrowed. First, a halogen containing a naphthalene ring, such as 1-halo-4- (trifluoromethyl) naphthalene, is prepared, and then a methylating reagent, such as a Grignard reagent such as methylmagnesium halide, is used for nucleophilic substitution at the 2,3-position of the naphthalene ring to promote the substitution of hydrogen atoms and then form the target product. This process requires attention to the control of reaction conditions, such as temperature and solvent selection. If the temperature is too high, it may cause a cluster of side reactions; if the solvent is not suitable, the reaction rate may be inhibited.
Second, the path of cyclization reaction can be considered. Starting with an appropriate chain compound, the structure should contain the necessary fragments for the construction of naphthalene rings, and there should be functional groups that can undergo cyclization reactions. With suitable catalysts and reaction conditions, the chain compound can be cyclized to construct a naphthalene ring structure, and methyl and trifluoromethyl can be introduced at the same time. If alkynes are used for metal-catalyzed cyclization, naphthalene rings can be constructed, and the required substituents can be introduced in suitable steps. However, in this method, the activity and selectivity of the catalyst are crucial, which are related to the success or failure of the reaction and the purity of the product.
Third, we can also start from the electrophilic substitution of aromatic hydrocarbons. The electrophilic substitution reaction of naphthalene ring is carried out with reagents containing methyl or trifluoromethyl. The naphthalene ring has certain nucleophilic properties due to its conjugate structure and can interact with electrophilic reagents. Trifluoromethyl is introduced first at the 4-position of the naphthalene ring, and then at the 1-position of the methyl group, and then through the reduction reaction, the 2,3-position double bond is hydrogenated to obtain 2,3-dihydro-1-methyl-4- (trifluoromethyl) naphthalene. However, the positioning effect of electrophilic substitution needs to be considered in detail to prevent the substitution position deviation and the product is impure.
This number method has its own advantages and disadvantages, and is selected according to various factors such as the availability of raw materials, the cost of the reaction, and the purity of the product.

2% 2C3-dideuterium-1-methyl-4- (trifluoromethyl) benzene. When storing and transporting this substance, the following general matters should be paid attention to:
First, when storing, it should be placed in a cool and well-ventilated place. This is because the substance may be volatile and unstable, and high temperature or poor ventilation can easily cause its properties to change, or even pose a risk to health safety. The temperature of the warehouse should be controlled within a suitable range, not too high, to prevent its volatilization from intensifying, and good ventilation can disperse the gas that may leak in time to avoid accumulation.
Second, it needs to be stored separately from oxidants, acids, bases, etc., and must not be mixed. Due to its chemical properties, contact with the above substances or cause severe chemical reactions, or cause serious consequences such as combustion and explosion. If the oxidant has strong oxidizing properties, contact with it or cause an oxidation reaction, resulting in a sudden rise in temperature and an increase in pressure.
Third, the storage area should be equipped with suitable materials to contain leaks. Once a leak occurs, it can be covered and absorbed with inert materials such as sand and vermiculite, which is convenient for subsequent proper treatment to prevent the spread of leaks and cause harm to the environment and personnel.
Fourth, the transportation process must ensure that the container does not leak, collapse, fall, or damage. If the packaging of the substance is damaged, the leakage will not only cause material loss, but also may pollute the environment and threaten the safety of transporters. Transportation vehicles should be equipped with the appropriate variety and quantity of fire equipment and leakage emergency treatment equipment. If there is an accident such as a leak on the way, it can be responded to in time to reduce the harm.
Fifth, when transporting, drive according to the specified route and do not stop in residential areas and densely populated areas. This can reduce the impact on many people in the event of an accident, and reduce the scope and degree of harm.
