Thiophenol → HCID 54270675, compound

Participants

Reaction Steps

30.88 g (108 millimols) of tetrachlorophthalic anhydride, 48.79 g (443 millimols) of thiophenol, 91.06 g (659 millimols) of potassium carbonate and 300 ml of tetrahydrofuran are stirred under reflux for 3 hours. The mixture is evaporated and the residue is taken up in methylene chloride/2N HCl solution. The organic phase is separated off, dried over sodium sulfate and evaporated. After recrystallisation from toluene/cyclohexane, 44.71 g (71% of theory) of tetrakis-(phenylthio)-phthalic anhydride are obtained; melting point 141°-2° C.
