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)

Sodium hydride reacts with thiols to form corrosive sodium thiolates. Hydrogen is likely produced in this reaction (Klemm, A., Hartmann, G. and Lange, L. 2000. Sodium and Sodium Alloys. Ullmann's Encyclopedia of Industrial Chemistry. (Online)).

Under certain conditions, sodium borohydride can reduce disulfides and polysulfides to produce thiols and thiolates. H2S could be produced if hydrogen disulfide (H2S2) is involved in the reaction, but probably will not be produced if other disulfides are involved instead (Eggeman, T. 2001. Hydrides. Kirk-Othmer Encyclopedia of Chemical Technology. (Online); Kammermeier, B. 2000. Reduction. Ullmann's Encyclopedia of Industrial Chemistry. (Online)).

Thiols may react with organolithium and organomagnesium compounds to liberate flammable hydrocarbon gases and metal thiolates (Carey, Francis. "Organic Chemistry", 5th Edition, Ch. 14. Accessed at: http://www.chem.ucalgary.ca/courses/351/Carey5th/Ch14/ch14-1.html#Reactivity).
