Hazard Predictions

• Corrosive: Reaction products may be corrosive
• Flammable: Reaction products may be flammable
• 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
• Toxic: Reaction products may be toxic

Sulfones with alpha-hydrogen atoms can be deprotonated by metal hydrides and alkyls such as Grignard reagents, sodium hydride, or butyllithium, with evolution of flammable hydrogen or hydrocarbon gases as well as toxic sulfur dioxide gas. The carbanions produced this way are strongly basic and reactive (Roy, K.-M. 2000. Sulfones and Sulfoxides. Ullmann's Encyclopedia of Industrial Chemistry. (Online)).

Sodium hydride reacts violently with DMSO (Urben, P.G. 1995. Bretherick's Handbook of Reactive Chemical Hazards, 5th Edition. Oxford: Butterworth-Heinemann., Vol. 1, pp. 349).
