title: Cu-catalyzed double S-alkenylation of potassium sulfide: a highly efficient method for the synthesis of various thiophenes.
abstract: An efficient synthetic approach to variously substituted thiophenes has been developed through copper-catalyzed tandem S-alkenylation of potassium sulfide with 1,4-diiodo-1,3-dienes.
