Hazard Predictions

• Generates gas: Reaction liberates gaseous products and may cause pressurization
• Generates heat: Exothermic reaction at ambient temperatures (releases heat)
• Intense or explosive reaction: Reaction may be particularly intense, violent, or explosive

Potassium reacts vigorously with dimethyl sulfoxide (Methoden der Organischen Chemie, Muller, E. (Ed.), Stuttgart, Georg Thieme, 4th ed., 1970. Volume 13.1. pp. 295).

Sulfones are cleaved by alkali metals to form metal sulfinate salts and highly basic metal alkyls. In the presence of proton sources, alkanes are produced (E. M. Kaiser, Synthesis, 1972, (8), p. 391-415).

The sulfonyl (-SO2-) group can be eliminated from sulfones by reducing agents such as alkali metals in ammonia or sodium amalgam. Sulfur dioxide is eliminated from unsaturated, cyclic sulfones by finely divided potassium (Roy, K.-M. 2000. Sulfones and Sulfoxides. Ullmann's Encyclopedia of Industrial Chemistry. (Online)).
