HYDROTHIOLYSIS OF DI(2-THIENYL) DISULFIDE

The thermal decomposition of 5-membered rings: A laser pyrolysis study

The mechanisms of pyrolysis of cyclopentadiene, furan, pyrrole and thiophene have been investigated using a combination of IR laser powered homogeneous pyrolysis, chemical and physical trapping of radical intermediates, and use of precursors specifically designed to generate selected radical intermediates. The results confirm the central role played by free radicals in the cases of cyclopentadiene and thiophene, and the dominant step of 1,2-H shifts in the cases of furan and pyrrole. The experimental results may be interpreted according to the high level ab initio calculations recently reported in the literature.

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.
