1423-27-4 - Introduction
2-trifluoromethylbenzeneboronic acid, chemical formula C7H5BF3O2, is an organic boron compound. The following is a description of its nature, use, preparation and safety information:
Nature:
2-Trifluoromethylphenylboronic acid is a colorless to yellowish solid that is readily soluble in polar organic solvents such as ethanol, dimethyl sulfoxide and dimethylformamide at ambient temperature. It has high thermal and chemical stability.
Use:
2-Trifluoromethylphenylboronic acid is often used as an important reagent in organic synthesis. It can be used as a fluorinating reagent for the introduction of trifluoromethyl groups in chemical reactions. In addition, it is also often used as a catalyst, ligand and intermediate, participating in organic synthesis reactions, such as Su g reaction and C- H activation.
Preparation Method:
2-Trifluoromethylphenylboronic acid can be prepared by the following method:
1. bromotrifluoromethane and phenylboronic acid are reacted under alkaline conditions.
2. Trifluoromethylphenylboronic acid and potassium carbonate are reacted under alkaline conditions.
These methods are usually carried out in an inert atmosphere or in an inert solvent.
Safety Information:
2-Trifluoromethylphenylboronic acid is relatively safe under normal conditions of use, but the following matters still need to be noted:
1. Use should wear appropriate protective equipment, such as chemical goggles and gloves.
2. avoid contact with skin and eyes, avoid inhalation or ingestion.
3. Pay attention to good ventilation conditions during operation.
4. storage should be sealed container, and placed in a cool, dry place, avoid contact with oxygen, water and acid and alkali substances.
Please note that the above information is for reference only. Please refer to relevant safety data sheets and operating procedures before specific use, and follow relevant laws and regulations.
