Conclusions

  1. 1.

    According to the data of kinetic study by UV and PMR spectroscopic methods, the formation of cis, cis-di(2-phenylvinyl) sulfide in the reaction between phenylacetylene and sodium hydrosulfide proceeds consecutive-parallel with the intermediate formation of cis-2-phenylvinylthiol, identified in the form of cis-2-phenylvinyl alkyl sulfides.

     
  2. 2.

    The rate constants at different temperatures and activation parameters of the consecutively-parallel reactions were estimated.

     
  3. 3.

    The formation of cis-2-phenylvinyl thiol is inhibited by water. At water concentrations in the range from 0.2 to 6 M, a rectilinear dependence is observed between the logarithms of the rate constants and the concentration of water.
