Sulfur-containing carboxylic acids: 6.* The syntheses of 3,3′-sulfinyldipropionic and 2,2′-sulfinyldiacetic acids

Pure sulfoxides of thiodialiphatic acids were obtained in high yields by oxidation of the corresponding sulfides in organic solvents. 3,3′-Sulfinyldipropionic acid was obtained by the reaction of hydrogen peroxide with thiodipropionic acid in acetone. 2,2′-Sulfinyldiacetic acid was synthesized by the reaction of thiodiglycolic acid with H2O 2 in acetone containing acetic acid (26 mol %). Pure 2,2′-sulfinyldiacetic acid was found to be stable in storage rather than labile as reported previously.
