    What is the synthesis method of 3,4-dihydro-1-phenylisoquinoline?
    To obtain 3,4-dichloro-1-naphthyl isobutyric acid, the following ancient method can be used.
    First, the naphthalene is taken as the starting material, and it is catalyzed with acryloyl chloride under an appropriate Lewis acid (such as anhydrous aluminum trichloride). The active part of the naphthalene can be electrophilically substituted with acryloyl chloride to obtain 1-naphthyl acrylic ketone. In this step, the ratio of the reaction temperature to the material needs to be controlled, and the temperature should be maintained at a low temperature to prevent side reactions.
    Then, 1-naphthyl acrylol ketone is reduced with a suitable reducing agent (such as sodium borohydride) to obtain 1-naphthyl propanol. The reduction conditions of sodium borohydride are relatively mild, which can accurately reduce carbonyl groups to hydroxyl groups, and has little effect on other unsaturated bonds in the molecule.
    The obtained 1-naphthyl propanol is then interacted with chlorination reagents (such as dichlorosulfoxide or phosphorus trichloride). After substitution reaction, the hydroxyl group is replaced by the chlorine atom to generate 1-naphthyl propyl chloride. This step is usually easy to carry out and the yield is considerable.
    Nucleophilic substitution of 1-naphthyl propyl chloride with sodium cyanide in an appropriate solvent is performed, and the chlorine atom is replaced by a cyanyl group to obtain 1-naphthyl propionitrile. After the introduction of cyanyl group, the molecular carbon chain can < Br >
    1-naphthalenyl propionitrile is then hydrolyzed, and under the catalysis of acid or base, the cyanyl group is converted into a carboxyl group, and the final 3,4-dichloro-1-naphthalenyl isobutyric acid precursor is obtained.
    Another idea is to chlorinate the naphthalene first, selectively introduce chlorine atoms at the 3,4 position, and then introduce isobutyric acid groups. However, the selective control of naphthalene chlorination is difficult, and suitable chlorination reagents and conditions, such as the use of a specific catalyst and the control of the reaction temperature and time, can increase the yield of 3,4-dichloronaphthalene. The subsequent steps are similar to the above, and the isobutyric acid structure is introduced through a series of reactions, and the The whole synthesis process requires fine control of the reaction conditions at each step to achieve the purpose of efficient synthesis.

    3% 2C4 is arsenic trioxide. This substance is highly toxic and relevant to its storage and transportation. There are many urgent precautions, as detailed below:
    - ** Storage **:
    - ** Isolated storage **: Arsenic trioxide must be stored separately from acids, alkalis, and edible chemicals, and must not be mixed. Due to its special nature, if it comes into improper contact with other substances, or reacts violently, it will cause safety accidents. If it encounters with acids, or produces toxic gases, it will threaten the safety of surrounding personnel and the environment.
    - ** Environment suitable **: It should be placed in a cool and ventilated warehouse. High temperature, humid environment or affect its stability, increasing the risk. The temperature of the warehouse should be controlled within an appropriate range, and the humidity should also be adjusted reasonably to ensure its chemical stability.
    - ** Clear signs **: Clear signs of toxic substances should be set up in prominent places in the storage place, stating key information such as "highly toxic" and "arsenic trioxide", so that personnel can see at a glance and know the danger immediately, so as to act with caution. At the same time, corresponding protection and emergency treatment equipment should be equipped to prepare for emergencies.
    - ** Special personnel management **: Arrange professional and trained personnel to be responsible for management. Management personnel should be familiar with the characteristics of arsenic trioxide, safety operating procedures and emergency disposal methods. Daily inspection of storage should be carried out regularly to see if the packaging is damaged, leaked, and whether the environmental conditions are normal.
    - ** Transportation **:
    - ** Qualification compliance **: Transportation enterprises must have dangerous chemical transportation qualifications, and vehicles, equipment, etc. must meet relevant standards. Drivers and escorts also need to undergo professional training, hold valid qualification certificates, and know the risks and countermeasures in transportation.
    - ** Tight packaging **: Arsenic trioxide should be packaged with materials and methods that meet national standards. Packaging must be sturdy and tight to prevent package damage and item leakage due to vibration, collision, friction, etc. during transportation. Clear dangerous goods signs should be affixed or tethered to the outside of the package.
    - ** Driving Caution **: During transportation, the driving route should avoid sensitive areas such as densely populated areas and water source protection areas. The speed should not be too fast to prevent sudden braking, sharp turns, etc. from causing the displacement of goods and damage to packaging. In case of bad weather, such as heavy rain, heavy fog, etc., it should be properly handled, or transportation should be suspended to ensure safety.
    - ** Emergency Preparedness **: Transportation vehicles should be equipped with necessary emergency rescue equipment and protective gear, such as gas masks, fire extinguishers, plugging tools, etc. At the same time, formulate and improve emergency plans, clarify the handling procedures and measures in case of emergencies during transportation, and organize regular drills to improve emergency response capabilities.
