Divinyl sulfide. Communication 12. Kinetics of the reaction of acetylene with sodium hydrosulfide in aqueous DMSO

The rate-determining step in the formation of divinyl sulfide in the reaction of acetylene with NaSH in aqueous DMSO is the addition of hydrosulfide ion to acetylene with the probable formation of sodium vinylthiolate; the addition of a second molecule of acetylene proceeds considerably more rapidly.
The rate constants for various temperatures and activation parameters for the formation of divinyl sulfide were measured.
An increase in the concentration of water in DMSO leads to a decrease in the NaSH concentration and an increase in the Na2S concentration; the yields of divinyl sulfide and 2,5-dimethyl-4-methylene-1,3-oxathiolane depend similarly on the water concentration.
In the reaction of acetylene with Na2S in aqueous DMSO divinyl sulfide is formed via two pathways, viz., from both SH− and S2− ions.
