THERMAL HYDROTHIOLYSIS OF DI(2-THIENYL)SULFIDE IN THE GASEOUS AND LIQUID PHASE

At 500-600 deg C, di(2-thienyl)sulfide is converted to thiophene, thiophene thiols, dithienyls, and dithienothiophenes, and isomerized to 2,3-dithienylsulfide.Hydrogen sulfide accelerates these reactions significantly.In the liquid phase the thermal conversion of di(2-thienyl)sulfide takes place only with the participation of elemental sulfur or in the system sulfur-hydrogen sulfide.Thiophene and diethienothiophenes are not formed in this case, while isomerization occurs to a large degree.The observed thermal conversions of di(2-thienyl)sulfide are based on the addition of thiyl radicals to the double bonds of the thiophene ring and to the sulfide sulfur atom.
