Sultone reaction
1,4-butanesultone reacts smoothly with nucleophiles such as ammonia to form the corresponding zwitterionic, usually very water-soluble sulfobutylbetaines. Sulfobetaines with longer alkyl chains (CnH2n+1 mit n > 10) show interesting properties as surface-active compounds (surfactants, detergents) with antimicrobial properties. WebThe reaction is characterized by a wide substrate scope, high efficiency, green solvent,… Synthesis of Novel α,β-Unsaturated Sulfonic Acid Derivatives Containing Dithiocarbamate/Xanthate Groups...
