Synthesis of cyclic 1,4-disulfides and alkylthiophenes by catalytic thiacyclization of acetylenes with sulfur

  • Published:
Bulletin of the Academy of Sciences of the USSR, Division of chemical science Aims and scope

Conclusions

  1. 1.

    The thiacyclization of mono- and disubstituted acetylenes with sulfur, leading to the production of dialkyl-1,4-dithiacyclohexa-2,5-dienes and thiophenes with high yield and catalyzed by the Co(acac)2-AlEt3 system in the presence of various ligands, is characterized.

  2. 2.

    The path of thiacyclization depends on the structure of the starting acetylene and the nature of the catalyst.
