Reaktionsschritte

2 g (4.46 millimols) of tetrabromophthalimide, 1.61 g (11.15 millimols) of p-chlorothiophenol, 2.31 g (16.73 millimols) of potassium carbonate and 20 ml of tetrahydrofuran are stirred at 25° C. for 14 hours. After acidification with dilute HCl solution, the mixture is extracted with tetrahydrofuran/toluene and the extracts are dried and evaporated. After recrystallisation from toluene/cyclohexane, 0.61 g (25% of theory) of 3,4,5-tris-(p-chlorophenylthio)-6-bromophthalimide is obtained; melting point 164°-9° C.
