Cu-Catalyzed Double S-Alkenylation of Potassium Sulfide: A Highly Efficient Method for the Synthesis of Various Thiophenes

[摘要]：An efficient synthetic approach to variously substituted thiophenes has been developed through copper-catalyzed tandem S-alkenylation of potassium sulfide with 1,4-dilodo-1,3-dienes.
