Participants

Reaction Steps

20 g (58.65 millimols) of tetrachlorophthalic acid N-n-butylimide, 33.64 g (243 millimols) of potassium carbonate, 13.57 g (123 millimols) of thiophenol and 150 ml of tetrahydrofuran are stirred at 25° C. for 18 hours. The mixture is acidified and extracted with methylene chloride. The extracts are dried and evaporated. After recrystallisation from toluene/cyclohexane, 23.88 g (83% of theory) of 4,5-bis-(phenylthio)-3,6-dichlorophthalic acid N-n-butylimide are obtained; melting point 215°-6° C.
