氯化甲基羰基硫 - Introduction
Methoxycarbonylsulfonyl chloride is an organic compound with the chemical formula CH3OCOSSCl. The following is a detailed description of the properties, uses, preparation and safety information of the compound:
Properties: Methoxycarbonylsulfonyl chloride is a colorless to pale yellow liquid with a pungent odor. The compound is stable at normal temperature and pressure.
Purpose: Methoxycarbonylsulfenyl chloride is commonly used as a reagent in organic synthesis. It can be used to introduce sulfonyl chloride groups into organic molecules and is commonly used in the synthesis of sulfonyl chloride esters. These compounds can further be used for the preparation of pharmaceuticals, pesticides and other organic compounds.
preparation method: methoxycarbonylsulfonyl chloride can be obtained by the reaction of methoxycarbonyl sulfonyl nickel dichloride and phosphorus trichloride. The specific preparation method is as follows:
1. Mix the methoxycarbonyl sulfonyl nickel dichloride and phosphorus trichloride according to the molar ratio.
2. Add the two reagents to a dry organic solvent, such as dichloromethane, under low temperature conditions.
3. Stir the reaction mixture and control the temperature between -20 and -10°C.
4. After the reaction is completed, the solvent is removed to obtain the product methoxycarbonylsulfonyl chloride.
Safety Information: Methoxycarbonylsulfonyl chloride is an irritating compound that can irritate the skin, eyes and respiratory system. Appropriate protective measures should be taken during operation, including wearing protective glasses, gloves and masks. Avoid inhaling its vapors or touching the skin. The compound is toxic to the environment and should be avoided in natural water bodies. Avoid contact with oxidants and strong bases during storage and use to prevent dangerous reactions.
