2-fluorobenzenesulfonyl chloride - Introduction
2-fluorobenzenesulfonyl chloride(2-fluorobenzenesulfonyl chloride) is an organic compound with the chemical formula C6H4ClFO2S. It has a colorless to light yellow liquid and is less volatile at room temperature.
2-fluorobenzenesulfonyl chloride is commonly used as an acid chloride reagent in organic synthesis. It can be used in the synthesis of organic compounds having an acid chloride functional group, such as sulfonyl chloride esters, acid chloride amines, and acid chloride ethers, etc. Since 2-fluorobenzenesulfonyl chloride can undergo nucleophilic substitution reactions in the reaction and is highly reactive to active nucleophiles, it has a wide range of applications in organic synthesis.
The preparation method of 2-fluorobenzenesulfonyl chloride can be obtained by fluorinating O-chlorobenzene and reacting with sulfinyl chloride. First, take the correct amount of O-chlorobenzene and fluorinate it using a fluorinating agent to produce O-fluorobenzene. O-fluorobenzene is then reacted with sulfinyl chloride to give 2-fluorobenzenesulfonyl chloride.
When using 2-fluorobenzensulfonyl chloride, it is necessary to pay attention to its toxicity and irritation. It is a sensitizing substance and has an irritating effect on the eyes and respiratory tract. Appropriate protective equipment such as gloves, goggles and masks must be worn during operation. In addition, it should be used under well-ventilated conditions and avoid contact with strong oxidants, strong bases or active metals to avoid dangerous reactions. Storage should avoid exposure to light, and placed in a sealed container, away from fire and high temperature.
