Direct access to thieno[3,4-b]thiophenes via elemental sulfur-promoted sulfurative tetramerization of acetophenones?
Chemical Communications Pub Date: 2022-11-08 DOI: 10.1039/D2CC05539B
Abstract
Thieno[3,4-b]thiophene cores could be conveniently obtained via one-pot sulfurative tetramerization of acetophenones using a ternary system comprised of elemental sulfur, a base and DMSO under simple heating conditions. The structure of the products was verified by X-ray crystallography.
