Efficient synthesis of organic sulfonic acid derivatives containing dithiocarbamate side chains

Abstract

An efficient method for the synthesis of organic sulfonic acid potassiums containing dithiocarbamate side chains was developed through the reaction of amines, carbon disulfide and sultones in the presence of K3PO4 in water at room temperature. The organic sulfonic acid potassium derivatives are easily transformed into the corresponding organic sulfonic acids, which were further reacted with amines to afford the important organic sulfonamides containing dithiocarbamate side chains.
