THERMAL TRANSFORMATIONS OF ALLYL 2-THIENYL SULFIDE AND SELENIDE

In the gas phase at 350-410 deg C allyl 2-thienyl sulfide is converted to thiophene-2-thiol, di(2-thienyl) sulfide, and 2-methylthienothiophene.In the presence of acetylene thienothiophene is formed in addition to these products.Allyl 2-thienyl selenide is converted quantitatively to 2,3-dihydro-2-methylselenophenothiophene during fractional distillation in vacuo.Thiophene, di(2-thienyl) selenide, di(2-thienyl) diselenide, thiophene-2-selenol, and 2-methylselenophenothiophene are formed in addition to these compounds in the thermolysis ofallyl thienyl selenide in the gas phase.In the presence of acetylene the thermal decomposition of allyl thienyl selenide is accompanied by the formation of selenophene.
