| Abstract: | A mechanism for the synthesis of divinyl sulfide via nucleophilic addition of the hydrogen sulfide anion to acetylene in the MOH (M = Na, K)/DMSO superbasic media has been studied using a quantum chemical approach. A comparative analysis of the consecutive stages of hydrogen sulfide and hydroxide anion addition to acetylene in the same catalytic systems is presented. |
