Conclusions

  1. 1.

    In the investigated series of acetylenic sulfides, sulfoxides and sulfones the maximum indications of conjugation are manifested between the sulfide sulfur and the C≡C bond.

     
  2. 2.

    The sulfonic group practically does not enter into conjugation with the triple bond, but it does polarize it, thus increasing the acidity of the acetylenic C-H bond.

     
  3. 3.

    In its effect on the triple bond the sulfoxide group occupies an intermediate position between the S and SO2 groups.
