HIGH-TEMPERATURE ORGANIC SYNTHESIS. XLII. REACTION OF HALOGENOARENES AND 2-CHLOROTHIOPHENE WITH HYDROGEN SULFIDE IN THE PRESENCE OF ACETYLENE

Benzothiophenes are formed with yields of more than 77percent in a single preparative stage during the gas-phase reaction of halogenoarenes with hydrogen sulfide and acetylene (600-700 deg C).It is suggested that arylthiyl radicals (ArS-radical), which are effectively captured by the acetylene, participate in the process.The effect of the structure of the halogenoarene on the selectivity of the process is discussed.The gas-phase reaction of 2-chlorothiophene with hydrogen sulfide in the presence of acetylene leads to the formation of thieno<2,3-b>thiophene.
