Potassium Carbonate → Tetrakis-(p-nitrophenylthio)-phthalimide

Participants

Reaction Steps

2 g (7.02 millimols) of tetrachlorophthalimide, 4.36 g (28.08 millimols) of p-nitrothiophenol, 5.82 g (42.12 millimols) of potassium carbonate and 30 ml of tetrahydrofuran are stirred at 25° C. for 14 hours. The mixture is acidified and extracted with tetrahydrofuran/toluene and the extracts are dried and evaporated. The residue is washed with methylene chloride and recrystallised from dioxane/toluene. This yields 3.02 g (57% of theory) of tetrakis-(p-nitrophenylthio)-phthalimide; melting point 297°-301° C.
