1-Allylcyclopropane-1-sulfonyl chloride(CAS: 923032-59-1)

1-Allylcyclopropane-1-sulfonyl chloride is a colorless liquid with a molecular weight of approximately 165.17 g/mol. It has a low solubility in water but is soluble in organic solvents. Chemically, it is highly reactive, particularly towards nucleophiles and can undergo substitution reactions. It crystallizes in the solid state and has a melting point around -35°C to -20°C. Due to its reactivity, it requires careful handling and storage under an inert atmosphere.

1-Allylcyclopropane-1-sulfonyl chloride is synthesized through the chlorosulfonylation of 1-allylcyclopropane. The reaction typically involves the use of chlorosulfonic acid in the presence of a Lewis acid catalyst such as aluminum chloride. The yield is generally good, and the reaction is carried out under an inert atmosphere to prevent unwanted side reactions.

1-Allylcyclopropane-1-sulfonyl chloride is used in the pharmaceutical industry for the synthesis of certain drugs. It also finds applications in the polymer industry for modifying polymer properties and in the electronics sector for the production of semiconductors. Its reactivity allows it to be used in various functionalization reactions, enhancing material properties and performance.

When handling 1-Allylcyclopropane-1-sulfonyl chloride, it is crucial to wear appropriate personal protective equipment (PPE), including gloves, safety goggles, and possibly a respirator. The substance should be stored in a cool, dry, and well-ventilated area, away from sources of heat and ignition. In case of a spill, it should be handled under a fume hood, and appropriate emergency response procedures should be followed. Always refer to the Safety Data Sheet (SDS) for detailed information and guidance.
