Description

Potassium Sulfide is reported to be used as a reactant for the efficient synthesis of variously substituted thiophenes through copper-catalyzed tandem S-alkenylation with 1,4-diiodo-1,3-dienes. It is also used as a reactant for the synthesis of KBi6.33S10 and K2Bi8S13 at high temperature.
