Reaktionsschritte

A mixture of 37 g (0.197 mole) of 2-(3,4-xylyl)thiophene, 200 ml of reagent carbon tetrachloride, 29 ml (36 g, 0.259 mole) of benzenesulfenyl chloride and 0.05 g of iron powder was allowed to stand two days at room temperature. A vapor phase chromatogram of the mixture showed that all the 2-(3,4-xylyl)thiophene had been consumed. The carbon tetrachloride was removed by distillation and the residue recrystallized from ethanol to give a first crop of 17 g (29%) of 2-phenylthio-5-(3,4-xylyl)thiophene, m.p. 77°-78° C.
