Conclusions
-
1.
It is shown that alkylthioamides can be synthesized in high yields by the reaction of elemental sulfur with alkylacetylenes in DMF solution, catalyzed by cobalt complexes.
-
2.
In the presence of phosphine, cyclooctasulfane and DMF complexes of cobalt are able to isomerize the inner triple bond in alkynes into the terminal position.
