Reaktionsschritte

The reaction was carried out in substantially the same manner as in Example 7, by using 27.2 g (0.075 mol) of the dipotassium salt of dodecylsuccinic acid as the initial materials (the salt was prepared in the manner described in Example 5), 33.3 g (0.075 mol) of tetraphosphorus decasulfide, and 9.3 g (0.3 mol) of red phosphorus, as well as 100 ml of dichlorobenzene as a solvent. The yield of dodecylthiophene was 48% (b.p. 196° C./20 mbar).
